GMP Standard Vhp Sterilize Pass Box with H2O2 Sterilize

Laminar flow delivery window is an auxiliary equipment for clean room used to pass small items between clean room and non-clean areas or clean rooms of different grades or different pressures. On one hand, it plays as an airlock to avoid high pressure in high-grade clean rooms from releasing; On the other hand, it can achieve self-purification in the pass process to ensure that the items entering the clean area are clean and reduce cross contamination; the blowing time can be adjusted manually to maximize the self-purification and save energy.

Basic Performance Requirements:

Cleanliness requirement in laminar flow delivery window: class B;

Double shell, arc treatment for inner periphery, seamless connection ensured;

Laminar flow designed with an upward air-sending & downward air-returning mode. The bottom is made of 304# stainless steel and punched, and integrates stiffeners;

Filter: G4 primary filter, H14 HEPA filter;

Wind speed: after HEPA filtration, wind speed at 0.38-0.57m/s (tested at 150mm below the uniform flow membrane);

Differential pressure function: pressure difference of the filter displayed (range: HEPA 0-500Pa/medium efficiency 0-250Pa), accuracy: ±5Pa;

Control function: fan on/off switch, with built-in electronic door interlock; UV lamp with an exclusive switch;

HEPA filter can be removed and mounted via top cabinet for easy maintenance and replacement;

Diffuse plate: made of 304# stainless steel screen
