Features and Benefits

Fire-Rated CleanMount® Pass-Through Chamber

Fire-rated pass-throughs protect personnel, equipment, and facility by maintaining the integrity of the fire-rated wall. They bear the UL 10B label for 90-minute fire exposure.

Removable Cart Ramps on Floor-Mount Models

Floor-mount pass-through chambers include dual-side stainless steel cart ramps, sloped on three sides, that are removable for easy cleaning.

All Stainless Steel FFU with Removable Filter Replacement Screen

The pass through includes an all-stainless steel filter fan unit with a screen for easy HEPA filter replacement. The screen is held in place by double roller catches, which allow the screen to be easily popped out of the ceiling to access the HEPA filter.

Recirculating HEPA Filtration Diagram

By recirculating the interior air, airborne particles are rapidly removed by successive passes through the HEPA filter. Recirculation also minimizes pressure buildup that can cause leakage into an adjacent positive-pressure cleanroom.

Interlock Status Lights

Prevent operator damage! A green light bar indicates the door is available for use, with the electronic interlock disengaged. The bar turns red when the opposing door is open to indicate the electronic interlock is engaged.

Wireless Door Alert

Alarm bell rings when its assigned door is open (two bells per chamber); plugs into a standard wall outlet.

CleanMount® Quick Install System

CleanMount® clamping design allows pass-through installation flush against a cleanroom wall in a few minutes, without drilling into the finished wall; mounting brackets clamp flush against walls of any thickness.

Flush-Mount Design Prevents Dust Accumulation

CleanMount® pass-throughs hug the cleanroom wall, eliminating gaps that collect germs and particle and making them ideal for critical bio/pharmaceutical cleanroom use.

Lift-Off, Non-Shedding Door Hinges

Non-shedding, barrel-type door hinges allow the doors to lift off for thorough cleaning and decontamination (no tools required). Unlike industry standard continuous designs, these hinges comply with strict ISO levels.

CleanMount® Lipless Chamber Eliminates Clearance Obstructions

Instead of welded seams, the corners of the CleanMount® pass-through interior are coved to eliminate dust and germ traps. The lipless opening presents no clearance obstructions and further simplifies cleaning.

Spring-Loaded Fire-Rated Passthrough Hinge

Spring-loaded hinges provide the self-closing capability required in a fire-rated wall. Automatic closing doors also simplify operation for operators with hands full.
