HEPA Filtered Pass Thru


Stainless steel pass through windows are ideal for the transfer of parts or equipment in and out of a cleanroom with an elimination of contamination and a reduction of "traffic."

Equipped with a Motorized HEPA Filter Unit

  • 120 V, 60 Hz, 0.83 Amps
  • 375 CFM air flow at 110 feet/min
  • Perforated inner sides for air recirculation


This cleanroom pass through window is constructed with a welded type 304 stainless steel, making it strong, sturdy, and easily cleaned while providing a superior look to your cleanroom. The all metal construction free of particle board also provides the durability to resist the warping, cracking, or chipping characteristics of formica which could then lead to the growth of biological contamination.

The doors are made with a heavy duty stainless steel frame, stainless steel continuous hinge, safety glass viewing window, closed cell PVC door gasket, and a Type 316 stainless steel lever compression door latches. The stainless steel frame adds strength and prevents cracking of the safety glass, a common problem with frameless doors.

Additional Options

Although this stainless steel version is equipped with a HEPA filter, it is also offered without a HEPA or with a light weight polypropylene construction. The poly version is only recommended when dealing with certain chemicals that are corrosive with stainless steel.
