Product Introduction

The canopy uses a floor-supported frame to carry a filtered overhead plenum above existing equipment. Its open sides permit carts, operators and maintenance tools to approach the process, while optional flexible curtains can be added where room drafts need greater control. Leveling feet and adjustable cross-members align the diffuser above the working footprint. Unlike a ceiling-suspended hood, the canopy transfers its load directly to the floor and can be repositioned after controlled disassembly.

Key Features

A self-supporting frame avoids structural loading of the building ceiling.

Open sides give technicians direct access to installed process equipment.

The overhead plenum can be sized to the actual clean-air footprint rather than the room area.

Leveling feet stabilize the frame on cleanroom floors with minor variation.

Optional flexible curtains reduce lateral mixing without creating permanent walls.

Customer Product Concerns

A local clean-air zone must fit around existing process equipment while keeping its support frame stable and outside normal operator movement.

The ceiling cannot carry a suspended filter plenum.A floor-supported aluminum or stainless frame carries the complete canopy load.

Permanent walls block maintenance access to the machine.Open sides and removable curtains preserve full process access.

A standard canopy does not match an irregular equipment footprint.Modular cross-members and filter sections follow the selected process dimensions.

Uneven floors twist the overhead diffuser plane.Adjustable leveling feet and bolted frame corners allow final alignment.

Typical Applications

Aseptic component stagingOpen filling-point protectionMedical-device assembly cellsClean inspection islands
