HEPA Supply Module (GSM): Ceiling-Integrated Clean Air Delivery
The HEPA supply module (GSM) is a field-proven, modular ceiling-integrated air-delivery unit meeting ISO Class 3–8 requirements. Built for engineering teams across Malaysia's regulated industries, it provides consistent airborne particulate control with a low-turbulence diffuser face and a leak-tested HEPA seal.
It integrates with our fan filter unit (FFU), high efficiency air outlet and HEPA supply module (PharmaSeal) ranges.

HEPA Supply Module (GSM) Construction
The fully welded downstream housing is the engineering secret. A GSM housing with a built-in GSF filter sealed in a jelly liquid tank delivers zero-leak operation and a Leak-Lead™ design — factory-pre-balanced with certified airflow reports and locking into the grid in under 90 seconds.
Why Choose Our HEPA Supply Module (GSM)
Zero-leak operation
Fully welded downstream housing and gel-seal filter give zero detectable leaks (DOP/PAO).
Factory-balanced airflow
Pre-balanced with certified airflow calibration reports for ±5% face-velocity uniformity.
90-second install
Rapid-deploy grid interface locks modules in under 90 seconds with no field cutting.
Aerosol challenge ready
Built-in aerosol challenge port supports in-place integrity testing and validation.
Integrated task lighting
Integrated LED task lighting (3,500 K, CRI > 90) for clear, true-color work areas.
Retrofit-friendly
Standard nominal sizes need zero modifications for retrofit and grid-deck projects.

Standing still creates purification "dead spots" where airflow cannot reach areas like back, underarms, and knees. Active rotation (at least one full turn) with arm movements ensures complete surface exposure
