Simplex offers several types of air venting and exhaust systems for either positive or negative pressure rooms. Proper vent selection depends on your contamination concerns, the level of clean, your physical layout, and other factors.
Deciding on a single pass or recirculating cleanroom depends on the environment that the cleanroom will be placed in, as well as the preciseness of temperature, humidity and pressurization controls.
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.
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.
Vinyl coated, non-particulating screen mesh is an option on vinyl inserts only.
Can be adjusted to accommodate airflow requirements.
Louvered grille available with pre-filter.
Framed open air space available with vinyl flap to seal opening where room is not pressurized.
Also known as a double wall system. Custom built on the interior or exterior of the cleanroom and include ABS adjustable sliding grilles
