Cleanroom Pass-Throughs & Air Showers

Simply put, pass-throughs keep “good” air in and “bad” air out of cleanrooms while minimizing foot traffic in and out of controlled environments. Also known as transfer cabinets or transfer chambers, pass-throughs are designed to be easy to clean and to further reduce the risk of cleanroom contamination.

Materials

Cleanability and durability are the most critical considerations for pass-through material selection. Available options include:

• Stainless steel (304 or 316)
• Powder-coated steel
• Polypropylene
• Static-dissipative PVC 
• Clear acrylic
• Lead lining

Configurations

Fully-welded body construction with smooth, formed-radius corners prevents particulate collection. We offer pass-throughs to fit your unique cleanroom setup:

• Wall-mounted
• Floor-mounted
• 90° pass-throughs
• Bio-design with knife-edge hatch openings
• Removable and lipless interior floors
• Active Pass Through (HEPA Filtered)

Door Selection

Pass-throughs are designed with a built-in interlock mechanism that prevents the interior and exterior doors from being opened simultaneously. Other door features include:

• Swing doors
• Double swing doors
• Sliding doors
• Manual or pneumatic operation
• Mechanical or electromagnetic interlocks

Compliance

ISO Class 1 through 8

USP 797 and USP 800

Air Showers and Tunnels

Air showers and tunnels use high-velocity jets of filtered air to remove particles and contaminants from surfaces before entering cleanroom environments. Air showers can be used for both personnel and objects, and they can also be integrated with cleanroom pass-throughs to maximize contamination control.

Features

• HEPA/ULPA filter units
• Stainless steel or powder-coated steel construction
• Swing doors with mechanical or electromagnetic interlock
• Occupancy for up to 7 personnel
• Customizable programming

Airflow Configurations

• Vertical or horizontal laminar flow
• Vertical or horizontal single-pass unidirectional flow
• Combined vertical and horizontal airflow

Pass-Through and Air Shower Integration: Modular Cleanroom Wall Systems

Our pass-throughs and air showers integrate with both structural and seamless-style cleanroom construction.

Structural Solutions

Structural systems can be constructed without tying into building infrastructure. These structures can be configured to support mechanical equipment & accommodate expansion; helping future-proof your investment.
