A cleanroom specification checklist is the short brief you complete before asking suppliers to quote — it captures the standard, size, airflow, components, validation and logistics that determine your cleanroom's design and cost. Working through it first means you receive accurate, comparable proposals instead of vague estimates, and you avoid the expensive redesigns that come from a half-defined scope.
Pak Gusu has distilled the questions our engineers ask on every project into a free, one-page PDF you can download, print and fill in. It is vendor-neutral — use it with any supplier — and it maps directly to ISO 14644 and EU-GMP so nothing important is missed.
Key takeaways
- Free one-page PDF — no email required — covering the six areas every cleanroom brief needs.
- Maps to ISO 14644 classes (5–8) and EU-GMP grades (A–D) so your spec is regulator-ready.
- A complete brief gets you accurate, comparable quotes and avoids costly mid-project redesigns.
- Vendor-neutral: use it with any cleanroom supplier, not just Pak Gusu.
- Pairs with our free cost calculator for a fast budget estimate before you commit.

What's inside the checklist
The checklist is organised into the six areas that drive every cleanroom design, cost and validation outcome:
| # | Section | What it captures |
|---|---|---|
| 1 | Application & standard | Industry, target ISO 14644 class, EU-GMP grade, your regulator, sterile vs non-sterile |
| 2 | Size & layout | Area, ceiling height, number of rooms, gowning/airlocks, personnel & material flow |
| 3 | Air & HVAC | ACPH target, HEPA grade (H13/H14), pressure cascade, temperature/humidity, monitoring |
| 4 | Envelope & components | Panels, fire rating, doors, pass boxes, air shower/FFU/LAF, flooring |
| 5 | Validation & documentation | IQ/OQ/PQ, ISO 14644-1 classification, HEPA integrity, as-builts, submission support |
| 6 | Project & logistics | Timeline, site/port, delivery terms (CIF/DAP), installation, approvals |
Not sure of an answer? Leave it blank — our engineers help you decide. See how the classes work in our ISO 14644 guide.
How to use it
- Download and print the one-page PDF (or fill it on screen).
- Work top to bottom — each section builds on the last; skip anything you can't answer yet.
- Send it with your enquiry. Attach it when you request a quote and you'll get a precise scope and price back, not a guess.
Why a complete spec saves you money
The biggest cost overruns in cleanroom projects come from briefs that change after design has started. Specifying one ISO class too clean wastes capital and energy on excess air changes and filtration; specifying too loose fails validation and forces a rebuild. A clear brief up front lets suppliers price the right room — and lets you compare quotes on a like-for-like basis.
It also speeds up your regulator submission: the same answers that define the build (class, grade, pressure cascade, validation scope) are what your DRAP, SFDA, MOHAP or other submission needs. Read more in our guide to cleanroom validation (IQ/OQ/PQ).
After you've filled it in
Two easy next steps:
- Estimate the budget with our free cost calculator — it uses the same ISO class and area you just defined.
- Request a tailored quote — send us your completed checklist and we'll respond with a precise scope, drawings and delivery schedule. Pak Gusu manufactures in Lahore and ships across Pakistan and the GCC.

Frequently Asked Questions
Common questions about cleanrooms, standards, cost and how Pak Gusu supplies and installs across the GCC.
Is the cleanroom specification checklist really free?
Yes. It is a free one-page PDF with no email or sign-up required — download it, print it and use it with any cleanroom supplier. We provide it because a well-defined brief leads to better projects for everyone.
Do I need to know every answer before downloading?
No. Fill in what you know and leave the rest blank. Items like ACPH, HEPA grade or pressure cascade are exactly what our engineers help you decide — the checklist is there to make sure nothing important is forgotten.
Which standards does the checklist cover?
It maps to ISO 14644-1 cleanliness classes (ISO 5 to 8) and EU-GMP Annex 1 grades (A to D), plus HEPA filtration (EN 1822 H13/H14), pressure cascade and IQ/OQ/PQ validation — the framework used across pharmaceutical, healthcare, food and electronics projects.
Can Pak Gusu help me complete the specification?
Yes. Send us whatever you have and our engineers will work through the open items with you, then return a complete scope. Manufacturing is in Lahore, Pakistan, with export and installation supervision across the GCC available at additional cost.
How do I get a quote once the checklist is filled in?
Attach your completed checklist when you request a quote on our get-quote page, or estimate the budget first with our free cost calculator. You'll receive a precise scope, drawings and a delivery schedule rather than a rough guess.
