Positive Pressure Isolation vs. Biohazard Containment

The Recirculating HEPA-Filtration version of the General-Use 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 slightly 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.

The status indicator lights confirm that the pass-through is operational. The installed Minihelic gauge measures backpressure at the HEPA filter in order to determine when a replacement filter is needed.

Pass-Through; EP 316L SS, CleanMount CleanSeam, 24"W x 24"D x 36"H, Isolated Interlock, Floor Mount w/Ramp

Pass-Through Chamber Interlock

Terra’s automatic mechanical interlock prevents cross-contamination by allowing one door to be open at a time. Encased in stainless steel, the mechanism is rated for millions of operations, more than enough to last the lifetime of the pass-through.

Stainless Steel Pass-Through LiftLatch™

Terra’s unique LiftLatches™ use leverage to apply force in a gentle, controlled manner, eliminating rotary motion used on other latches that strain wrists and door hinges. The LiftLatch snaps into place to produce a positive seal.

Stainless Steel Reinforced Doors and Handle

Doors on professional-grade pass-through chambers are reinforced with stainless steel frames, which lend rigidity, improve the seal, and extend the service life of the doors.

Recirculating Passhtrough Speed control knob

Speed control knob allows adjustment of the blower RPM, increasing the airflow and pressure within the chamber.

  • CleanTop™
    The CleanTop™ is designed for installations that require the chamber to be centered in the wall. The 30° sloping top on the cleanroom-side minimizes particle accumulation and accommodates laminar downward airflow.
