Pacific Environmental Technologies pass through chambers are available in a variety of sizes and configurations to meet the most basic and complex applications, but can also be custom ordered to meet YOUR specific requirements. 

Pass through chambers are available in standard sizes ranging from 12”W x 12”D x 12”H to 40”W x 48”D x 48”H for installation above the finished floor or floor mounted. Floor mounted pass through chambers feature a small built-in low profile ramp to allow materials being transferred by cart to be easily pushed into and pulled out of the pass through chamber. 

A mechanical interlocking mechanism is standard all Pacific Environmental Technologies, Inc. pass through chambers, which controls cross-contamination by allowing only one door at a time to be opened. These interlocking mechanisms are maintenance free and require no electrical power to operate. As helpful as pass through chambers are in controlling cross contamination, it is sometimes necessary to go a step further to ensure that the cleanliness of your cleanroom isn’t compromised. That’s why we provide units with a HEPA or ULPA filter air shower purging for enhanced particle control. The HEPA or ULPA filter option can be provided with a built-in blower unit or with a non-powered HEPA or ULPA unit for connection to an in-house air handling system.

Pass through chambers help in the following ways:

1. Helps to control contamination within the cleanroom by eliminating unnecessary personnel entry 
2. Allows for quick and convenient transfer of materials between adjoining cleanrooms or from a non-cleanroom to a cleanroom area
3. Saves valuable time by eliminating the need for gowning and de-gowning of personnel bringing required material, parts, etc., to the cleanroom 

Standard materials used by Pacific Environmental technologies, Inc. in fabricating pass through chambers are:

     A. Laminated Formica (non-conductive and conductive)

     B. Acrylic (Clear, amber, smoked, etc.)

     C. PVC (non-dissipative and ESD safe static dissipative)

     D. Polypropylene

     E. Stainless Steel (304 and 316)

     F. Electro Polished Stainless Steel (304 & 316)

The following pictures show a variety of standard pass through chambers, all of which can be ordered to suite your needs:

LAMINATED FORMICA

Shown here is a 24”W x 24”D x 24”H small parts pass through chamber and a 30”W x 36”D x 40”H cart pass through chamber each with PVC doors

Small parts pass through with white powder coated mounting bracket and PVC doors

POLYPROPYLENE

This pass through chamber was built to accommodate a custom stainless steel cart fabricated by the customer to move its product between two cleanroom areas

Small built-in ramp shown here in the adjacent room where the cart at left is being transferred

Cart pass through chamber with top mounted motorized fan/HEPA filter module

Polypropylene housing accommodates the motorized fan, HEPA filter media and easy access top mounted pre-filter

STAINLESS STEEL

Cleanroom side of an extra wide cart pass through chamber fabricated out of 304 stainless steel, which is installed within a pharmaceutical compounding facility

Built-in magnehelic gauge displays the pressure differential after adjustment of the lower slide dampers located on both sides of the pass through chamber. HEPA filtered air for pressurization is provided by a dedicated in-house air handling system

Side mounted variable speed motorized fan/HEPA filter module provides the needed clean air and the lower slide dampers located on the doors provide pressurization adjustment

The tapered and perforated top provides a work surface for IPA wipe downs with excess IPA dripping through to built-in lower caught basin, then gravity drains to remote container. Caught basin is easily cleaned via the hinged work surface
