The cost of a cleanroom in Pakistan is driven mostly by your target ISO 14644 class and the air-change rate (ACPH) it demands, then by area and layout, the wall and ceiling system, HVAC and HEPA filtration, finishes, doors and pass-boxes, controls, and the depth of validation your project requires. Two rooms of identical floor area can differ several times over once these factors are fixed, which is why no responsible manufacturer can quote a meaningful number from a single square-metre figure.
Pak Gusu Technology (Pvt) Ltd is a cleanroom manufacturer with its factory in Lahore and the technical partner of GUSU Purification (China). We deliberately publish no fixed prices on this page, because every cleanroom is engineered to order around your classification, process and regulatory submission. Instead, this guide explains exactly where the money goes so you can brief us accurately.
To turn these drivers into a budgetary figure for your own room, use our cleanroom cost calculator, then request a formal, itemised quotation. The calculator is the only place on this site that computes money; everywhere else we discuss the engineering factors behind it.
Key takeaways
- ISO class and the resulting air-changes-per-hour (ACPH) are the single biggest cost lever, mostly through HVAC and HEPA capacity rather than the panels themselves.
- Area, ceiling height and layout complexity (airlocks, pass-boxes, gowning) drive panel quantity, structure and the air volume to be conditioned.
- Finishes, the wall/ceiling core, doors, controls and validation scope each move the budget independently of floor area.
- Locally manufactured versus imported components changes lead time and landed cost; we can balance both around your specification.
- Pak Gusu publishes no fixed prices because every cleanroom is built to order; use the cost calculator for a budgetary estimate.
- Rooms are engineered to suit ISO 14644 and EU-GMP and to support your DRAP submission and IQ/OQ/PQ, not sold as pre-certified.
Why we publish no fixed cleanroom prices
A cleanroom is not a catalogue product with a shelf price. It is a built-to-order air-handling and architectural system whose cost is set by the cleanliness class you must hold, the process inside it, and the documentation your regulator expects. The same 100 m² footprint can be a modest ISO 8 packaging area or a unidirectional-flow ISO 5 aseptic core, and those two rooms sit at completely different points on the cost curve.
Because of that, any single price or rate you see advertised is, at best, a placeholder that ignores your real requirements. We would rather give you the honest mechanics of cost and then quote precisely against your drawings. When you are ready for a number, the cleanroom cost calculator produces a budgetary estimate from your class, area and scope, and our team converts that into a firm itemised quotation.
The main cost drivers, ranked by impact
The table below summarises how each factor typically influences a Pakistan cleanroom budget. Impact is shown as a low, medium or high relative effect, with no monetary figures, because the actual weighting shifts with your class and scope.
| Cost driver | What it controls | Relative impact |
|---|---|---|
| ISO class & ACPH | Air changes, HEPA coverage, HVAC capacity and energy load | High |
| HVAC & HEPA filtration | Air handling units, ducting, terminal H13/H14 HEPA, pressure cascade | High |
| Validation scope | IQ/OQ/PQ, particle counts, airflow visualisation, requalification | High |
| Area & layout | Total m², ceiling height, number of rooms, airlocks, gowning | Medium |
| Wall/ceiling system | Panel core (PU, rockwool, honeycomb), walkable ceiling, coving | Medium |
| Finishes | Flooring (epoxy/vinyl), vision panels, integrated lighting, sealing detail | Medium |
| Doors & pass-boxes | Hermetic/interlocked doors, pass-through chambers, air showers | Medium |
| Controls & monitoring | BMS, pressure/temperature/RH monitoring, alarms, interlocks | Medium |
| Local vs imported components | Lead time, landed cost and availability of spares | Low–Medium |
Notice that the three highest-impact rows all flow from one decision: the ISO class. Fix that correctly first and the rest of the budget falls into a sensible band. Our guide to ISO 14644 classes explains how to choose, and the cleanroom glossary defines the terms used here.
How ISO class and ACPH drive everything downstream
Air changes per hour (ACPH) is the number of times the full room air volume is replaced each hour, and it is the core HVAC figure for any cleanroom. Higher cleanliness classes demand far more air changes: an ISO 8 space runs a modest ACPH, while an ISO 5 / EU-GMP Grade A zone needs near-full HEPA ceiling coverage and unidirectional (laminar) airflow. Each step up multiplies fan capacity, filter count and the cooling duty your HVAC must deliver.
Note that the EU-GMP grade depends on whether the room is assessed at rest or in operation, so the comparison below is indicative rather than a fixed one-to-one mapping:
- ISO 8 (broadly Grade C at rest / Grade D in operation): lower ACPH, turbulent (non-unidirectional) flow, partial HEPA coverage, lighter HVAC.
- ISO 7 (broadly Grade B at rest / Grade C in operation): higher ACPH, more terminal HEPA, a stricter pressure cascade.
- ISO 5 (Grade A, and Grade B at rest): very high air supply, near-total H14 HEPA ceiling, unidirectional flow and full EU-GMP Annex 1 rigour for aseptic work.
Because most of the step-change is in air handling and filtration, not panels, the HVAC and fan-filter unit selection is where you should focus when comparing budgets. You can size the indicative ACPH, airflow and HEPA count for your own room in the cost calculator.
Building fabric: panels, ceilings, doors, pass-boxes and finishes
The architectural envelope is the second cluster of drivers. The wall and ceiling system you choose, the way it is finished, and the openings within it all change the build.
- Wall/ceiling panels: core type (PU sandwich, rockwool for fire rating, honeycomb for rigidity) affects cost and performance; see our cleanroom panels.
- Coving and sealing: radiused coved corners and flush detailing aid cleanability and matter more at higher grades.
- Doors: hermetic, interlocked and vision-panel cleanroom doors add cost but support the pressure cascade.
- Pass-boxes and air showers: pass-through chambers and an air shower control contamination at entry points.
- Finishes: epoxy or welded vinyl flooring, integrated lighting and laminar units such as a laminar air flow unit for critical zones.

Local versus imported components for a Pakistan project
For a cleanroom built in Pakistan, the local-versus-imported mix is a genuine cost and schedule lever rather than a quality compromise. As a Lahore-based manufacturer and the technical partner of GUSU Purification (China), we can specify components from either route to balance landed cost, lead time and spares availability.
- Locally manufactured: panels, doors and steelwork produced at our factory shorten lead times and simplify after-sales support within Pakistan.
- Imported specialised items: certain HEPA media, instrumentation and high-grade HVAC components may be sourced internationally where performance or qualification demands it.
- Lead-time planning: imported elements need scheduling ahead; we flag these early so your programme stays realistic.
Installation supervision is available at additional cost and is quoted separately from supplied goods, which keeps your budget transparent. See our services for how supply and site support are structured. If your project also spans the Gulf, our cleanroom GCC page covers how we serve those markets.
What to check and common concerns before you budget
Buyers most often under-budget validation and energy, and most often over-specify the class. Before you commit a number, sanity-check these points.
- Confirm the class against the process, not aspiration: paying for ISO 5 where ISO 7 suffices is the most expensive avoidable mistake. We help you right-size it.
- Separate supply from installation: our core scope is manufactured goods; on-site installation and supervision are an additional, separately quoted line.
- Budget validation explicitly: IQ/OQ/PQ, particle counts and requalification scale with grade, not floor area.
- Account for running cost: high-ACPH rooms run HVAC continuously, so energy is a real lifetime line item in Pakistan's climate.
- Plan spares and consumables: periodic HEPA replacement and gauge calibration keep a validated room compliant.
- Be wary of fixed advertised prices: a credible number comes only from your drawings and regulatory target, which is why we quote rather than list.
When these are clear, the cost calculator gives a budgetary band and we follow up with a precise quote.
Standards and regulatory framing in Pakistan
Cleanroom classification in Pakistan follows the international standards: ISO 14644 for airborne particle classes and EU-GMP Annex 1 for sterile pharmaceutical manufacturing. Filtration is specified to EN 1822 (HEPA H13/H14), and contamination control relies on a properly designed pressure cascade between adjacent classified spaces.
For pharmaceutical and nutraceutical facilities, the national regulator is the Drug Regulatory Authority of Pakistan (DRAP), and Pakistan is a PIC/S applicant. We design and document our cleanrooms to suit ISO 14644 and EU-GMP and to be validation-ready: we engineer to support your DRAP submission and your IQ/OQ/PQ, but we do not claim to hold certifications or approvals on your behalf, those remain between you and your regulator. See our pharmaceutical & nutraceutical page and our validation (IQ/OQ/PQ) overview for how qualification scope influences both compliance and cost.

Frequently Asked Questions
Common questions about cleanrooms, standards, cost and how Pak Gusu supplies and installs across the GCC.
How much does a cleanroom cost in Pakistan?
There is no single fixed price, because every cleanroom is built to order. Cost is driven mainly by your ISO class and air-changes-per-hour, then by area and layout, the wall and ceiling system, HVAC and HEPA filtration, finishes, doors, controls and validation scope. We publish no fixed prices here; use our cleanroom cost calculator for a budgetary estimate, then request a formal itemised quotation.
Why does ISO class affect cost so much more than floor area?
Because class sets the air-changes-per-hour, which in turn sets HVAC capacity and HEPA coverage. Moving from ISO 8 to ISO 5 multiplies fan capacity, filter count and cooling duty, while the panels barely change. Most of the step-change in cost sits in air handling, filtration and validation rather than in the building fabric, so getting the class right is the most important budget decision.
Is installation included in a cleanroom quote?
No. Our core scope is the manufactured cleanroom goods supplied from our Lahore factory. On-site installation and supervision are available at additional cost and are quoted separately, which keeps your budget transparent and lets you control the install scope. You can also engage a local contractor for fit-out if you prefer.
Should I choose locally made or imported cleanroom components?
It depends on lead time, landed cost and the performance or qualification a given item needs. As a Lahore-based manufacturer and the technical partner of GUSU Purification (China), we produce panels, doors and steelwork locally for faster delivery and support, and source specialised HEPA media or instrumentation internationally where required. We flag long-lead imported items early so your programme stays realistic.
Are Pak Gusu cleanrooms certified for DRAP or GMP?
We do not claim to be GMP or DRAP certified. We design and document our cleanrooms to suit ISO 14644 and EU-GMP Annex 1, and we engineer them to be validation-ready and to support your DRAP submission and IQ/OQ/PQ. Certification and regulatory approval remain between you and DRAP; our role is to deliver a room and documentation package that supports your case.
How do I get an actual estimate for my cleanroom?
Use our cleanroom cost calculator to generate a budgetary band from your ISO class, area and scope, including the indicative air-changes and HEPA fan-filter units you will need. Then request a quote and our engineers return a formal, itemised quotation built around your drawings, process and regulatory target.
