Air Mixing Module System

Air Mixing Module System

A "Clean" way to eliminate mixing fans inside the isolator

  • Ideal for applications where adequate VHP gas distribution is difficult to achieve
  • Mixing fans are inside the isolator during the VHP decontamination, not when your product is there
  • The configurable air mixing assembly is housed within a dedicated NRC Canister
  • Mechanical configuration assures repeatability to the validated fan position
  • Easily customizable to the requirements of the application
  • Presentation

System Description

A system that docks onto a standard RTP port of the barrier isolator for the purpose of creating air turbulence within the isolator chamber during Vapor Hydrogen Peroxide (VHP) decontamination.

The system consists of a Non-Rotating Canister (NRC) containing three fans that are extended out of the canister body and into the isolator chamber before starting the VHP cycle. The three fans are attached to a manually actuated shuttle that is housed inside the NRC. This method of attachment results in repeatable positioning and orientation between VHP cycles.

Two fans are mounted on individual swing arms that reach well into the isolator system. A third fan, hard mounted to the shuttle mechanism, creates air turbulence in front of and within the NRC thus assuring good VHP coverage of internal surfaces.

At the end of the VHP cycle, the fans are stowed back into the NRC by the operator through the isolator gloves. The design of the system is such that the stowing operation can be accomplished by touching surfaces that have been decontaminated by the VHP cycle.

System Set up Schematics

  • Step 1 Step 1 Air mixing module NRC is docked to the Alpha port of the isolator
  • Step 2 Step 2 The Alpha/Beta door is opened to gain access to the fan slid inside the NRC
  • Step 3 Step 3 The fan skid is pulled out of the NRC. The stroke is fixed and set by hard stops
  • Step 4 Step 4 Fans 1 and 2 are raised to the upright position. The extent of the swing is set by hard stops to assure of positioning repeatability.
  • Step 5 Step 5 Fans 1 and 2 are moved to the validated angular position and orientation. They are locked in position to assure of repeatability. Fan 3 is not adjustable.
  • Electrical Electrical The power cord penetrates the canister body via a leak tight bulkhead connector. Wiring to the individual fans is routed within the mounting arms.
