Product Introduction

The 305 x 610 x 109 mm format doubles the published airflow of the square quarter module while retaining the same 55 Pa initial drop. Its elongated face suits narrow ceiling lanes and process enclosures that cannot accept a 610 mm-wide full module. An integral knife edge is formed into the frame for direct engagement with a compatible gel grid.

Key Features

Narrow-bay coverage

The half-width footprint follows linear ceiling zones without forcing oversized cutouts around adjacent services.

Proportional airflow step

The longer face carries 300 m3/h at the documented 55 Pa starting resistance.

Direct fluid-seal interface

The knife-edge perimeter mates with a gel receiver for room-side or common-plenum installation.

Applications

Intended for narrow common-plenum ceilings, laminar-flow canopies and equipment bays needing approximately 300 m3/h of H14 supply. The rectangular panel should be oriented to preserve uniform downstream airflow and unobstructed room-side access for removal.

Solutions for Your Application

A 305 mm square panel cannot deliver the required flow without excessive face velocity.The 610 mm length doubles rated flow to 300 m3/h while retaining the 55 Pa starting drop.

The elongated element twists while being inserted into the gel grid.Support both short ends, keep the frame level and engage the knife edge vertically to avoid disturbing the gel path.

Available Options

Specify exact grid opening, knife-edge face, downstream screen, airflow direction and handling tabs for the narrow module.
