wall-mount model No. 6705-72 (support brackets recommended on opposite side). 
Recirculating HEPA-filtered pass-through,
floor-mount model No. 6705-68

  • Double-walled 304 stainless steel construction creates plenum chambers for recirculating HEPA-filtered air
  • Air return slots along the bottom of the chamber circulate air back through the HEPA filter
  • Speed control knob lets users adjust the blower RPM, increasing the airflow and pressure within the chamber
  • Flush mounting on the "clean" side reduces horizontal surfaces that collect particles
  • HEPA filter removes contaminating particles of 0.3 um or larger at 99.99% efficiency
  • Brushless DC fan motor is clean, quiet and energy-efficient
  • Choose between wall-mount and floor-mount models to fit your workflow
The stainless steel screen in the ceiling can be removed for HEPA filter replacement.  Return vents are positioned along the bottom of the chamber to pull airflow back to the blower.

The Recirculating HEPA-Filtration version of the Smart Pass-through adds another layer of protection against contamination for materials being transferred.  A blower/filter module emits a continuous, laminar flow of HEPA-filtered air from the ceiling that prevents airborne contamination from reaching senstive materials.

When run continuously, this micro-filtration system sweeps away any particles that may enter the transfer chamber when the doors are opened and maintains an extremely clean pass-through environment.  The blower also slighly pressurizes the chamber, similar to the ISO-classified positive pressure utilized in a cleanroom.  Because the pressurization is minimal, the pressure gauge on the unit measures the backpressure at the filter, which can be used to monitor its efficiency and remaining filter life.

As with all Smart Pass-throughs, the status indicator lights confirm that the pass-through is operational and the LED light bar indicates when the interlock is engaged. Audible chimes will also sound when a pass-through door is opened, alerting personnel on the other side. The installed Minihelic gauge measures backpressure at the HEPA filter in order to determine when a replacement filter is needed. Wall support brackets are recommended to support chamber weight (order separately).

Also available: Smart Pass-Through™ with single-pass ULPA-filtered air shower for surface removal of particles and debris.
