Air recirculates through a HEPA
filter fan module to remove
sub-micron contaminants

Remove particles and other surface-deposited contaminants with this flush-wall mounted, recirculating air shower pass-through, which features 304 stainless steel chamber construction and HEPA filter/fan module to remove particles 0.3 um or larger, with 99.99% efficiency.

This micro-filtration system continuously scrubs chamber environment to remove any particles that may enter the transfer chamber when the dirty-side access door is opened, or that may be deposited on the transferred parts.

Just close the electronic inter-locking door and set the timer to commence the shower cycle. Air is directed down and forced through return slots at chamber floor. Air then recirculates up and back down through the HEPA filter. Doors remain locked on both sides until the air shower is complete. 

Status indicator lights confirm that the air shower pass-through is operational. Audible chimes will sound when the air shower cycle is complete, lalerting personnel that doors are ready to be opened. The 24" x 16" fan/filter unit features a Challenge Port for measuring pressure with a differential gauge, and introducing aerosols for leak testing. Wall support brackets recommended to support chamber weight (order separately).

Also available: Smart Pass-Through™ with single-pass air shower.
