SINGLE PASS vs. RECIRCULATING CONFIGURATION
Which configuration is right for you?
We offer several types of air venting and exhaust systems for either positive or negative pressure rooms
Proper vent selection — Deciding on a single pass or recirculating cleanroom depends on the environment that the cleanroom will be placed in, contamination concerns, the preciseness of temperature, humidity and pressurization controls, and other factors.
- SINGLE PASS CONFIGURATION
A single pass room is a simple design in which air is pumped into the room from the top and blown out the vents at the bottom.
- RECIRCULATING CONFIGURATION
A recirculating design uses a plenum system or air chase system (or both) to recirculate the air that passes out of the vents at the bottom of the room back into the room.
