- Modular Wall Systems : Pre-engineered modular wall systems commercial builds with internal utility channels and smooth flush finishes.
- Coving & Panels: Non-corrosive aluminum cleanroom framing and heavy-duty steel cleanroom panels
- Walkable Ceiling Systems: Heavy-capacity load bearing cleanroom ceiling options allowing top-side maintenance without disturbing cleanroom operations, as well as flush cleanroom ceiling grid frames.
These details may seem minor, but in a regulated environment, every detail contributes to validation success.
Cleanroom Furniture & Stainless Steel Fixtures
-
Cleanroom Gowning Bench: Ergonomic cleanroom gowning bench entry transitions separating restricted and non-restricted zones.
-
Tables & Workbenches: Heavy-gauge stainless steel cleanroom table setups and modular cleanroom bench workstations.

- Acoustic Controls: Specialty acoustic enclosures, industrial soundproofing panels, modular sound booths, and noise barrier walls outdoor for equipment containment.
Flush Cleanroom Doors & Vision Panels
-
Cleanroom Doors: Single and double cleanroom doors with active interlock systems, perimeter magnetic seals, and drop-down bottom seals to maintain pressure cascades.
-
Flush Cleanroom Doors: Completely level flush cleanroom doors that eliminate ledges where bacteria and particulates accumulate.
-
Cleanroom Windows: Double-glazed cleanroom windows (vision panels) mounted flush with wall surfaces, complete with desiccant systems to prevent condensation.
Contamination Airlocks, Flooring & Coving
-
Cleanroom Air Shower: High-velocity cleanroom air shower entry corridors with adjustable HEPA nozzles to strip surface particulates from personnel before entry.
-
Cleanroom Pass-Through Chambers: Stainless steel cleanroom pass through units and mechanically interlocked cleanroom pass box cabinets for safe, cross-contamination-free material transfer between clean rooms.
-
Epoxy Cleanroom Floor: Seamless, chemical-resistant epoxy cleanroom floor coatings and ESD-safe static-dissipative floor systems.
- Cleanroom Coving: Radiused cleanroom coving connecting wall-to-wall, wall-to-floor, and wall-to-ceiling transitions to eliminate 90-degree corners.
Mechanical Engineering, HVAC & Air Filtration Solutions
Maintaining exact particulate counts and environmental parameters requires robust mechanical design. ACH Engineering provides complete mechanical engineering and replacement HVAC equipment:
Air Filtration & Workstations
- FFU Cleanroom (Fan Filter Unit): Ceiling-integrated FFU cleanroom (fan filter unit) modules equipped with variable speed motors and high-efficiency cleanroom HEPA filter media (99.99% @ 0.3μm).
- Laminar Flow Hood Workstations: Standalone vertical and horizontal laminar flow hood stations for localized, sterile micro-assembly.
- Custom Cleanroom HVAC System Design: End-to-end cleanroom HVAC system design and specialized HVAC for cleanrooms featuring dynamic thermal zoning, dehumidification, and custom ducting.
Pressure Cascades & Air Changes Per Hour
ACH Engineering implements automated controls for cleanroom positive vs negative pressure environments:
- Positive Pressure Cleanrooms: Pushes clean air outward to keep external shop-floor dust and particulates out of critical electronics, optical, or battery processing zones.
- Negative Pressure Cleanrooms: Pulls air inward toward HEPA exhaust systems to safely contain chemical vapors, active powders, or dangerous fumes.
All mechanical systems are engineered according to strict cleanroom air changes per hour chart requirements, from 10–25 ACH for ISO 8 industrial spaces to 240–480 ACH for ISO 5 environments.

Frequently Asked Questions
Does ACH Engineering supply individual cleanroom components in addition to turnkey builds?
Yes. While we provide end-to-end cleanroom design, construction, and certification, we also supply standalone cleanroom hardware across Toronto and the GTA. This includes cleanroom pass-throughs, air showers, replacement fan filter units (FFUs), flush cleanroom doors, modular wall panels, and stainless steel laboratory furniture.
What is the difference between softwall vs hardwall cleanrooms?
A hardwall cleanroom utilizes rigid modular wall panels (steel, aluminum, or FRP) to create a completely sealed, pressure-controlled space required for high-stringency ISO 5–7 and cGMP applications. A softwall cleanroom uses flexible, clear PVC strip curtains hung from a structural frame; it provides a cost-effective, portable option for localized ISO 7–8 process protection where rigid air pressure containment is not required.
What is the difference between ISO 7 and ISO 8 cleanrooms?
The primary difference between ISO 7 and ISO 8 cleanrooms involves allowable airborne particle concentration and air exchange rates. An ISO 7 environment permits up to 352,000 particles per cubic meter and requires 30 to 60 air changes per hour. An ISO 8 environment permits up to 3,520,000 particles per cubic meter and requires 10 to 25 air changes per hour.
What steps are involved in the cleanroom validation and certification process?
Our engineering specialists guide facilities through the entire cleanroom certification process and execute full cleanroom validation protocol testing (IQ/OQ/PQ). This includes HEPA filter integrity testing (PAO leak testing), airborne particle count verification, air velocity testing, room pressure differential confirmation, and complete documentation for regulatory compliance audits.
