STjh 300 CFM positive-pressure HEPA supply module with broad diffuser, duct collar and pressure gauge

STJH-POSITIVE-PRESSURE-HEPA-SUPPLY-300CFM

Positive-Pressure HEPA Air Supply Unit 300 CFM

A mid-size 300 CFM HEPA supply module for laboratory and pharmacy positive-pressure duty.

610 x 610 mm module face
300 CFM filtered supply
Mid-range pressure duty

Introdução do produto

With a 610 x 610 mm face and 650 mm depth, this module occupies the middle position between the compact and large positive-pressure units. It supplies 300 CFM of HEPA-filtered air sourced from an adjacent area. The larger casing supports a moderate clean-air contribution for preparation rooms that have outgrown the 200 CFM format but do not need the 500 CFM enclosure.

Características-chave

Balanced mid-range format

The 300 CFM duty adds make-up capacity without the footprint of the 740 mm class unit.

Partition-ready square face

A 610 mm square module front integrates naturally with common cleanroom panel geometry.

Filtered pressure support

The internal HEPA stage separates incoming adjacent-area particles from the clean-side discharge.

Applications

Recommended for pharmacy preparation rooms, medium laboratory suites and clean support spaces that need a stable 300 CFM filtered supply. Pressure performance depends on leakage area and the selected room relief device.

Solutions for Your Application

The 200 CFM module cannot overcome normal room leakage.Move to the 300 CFM cabinet and balance its discharge against measured leakage and relief airflow.

A poorly shaped discharge can create local drafts.Select a diffuser arrangement that distributes the module's output across the occupied zone.

Opções disponíveis

Select filter grade, diffuser, inlet screen, controls, mounting trim and supply voltage. Size the transfer source and relief opening for the intended pressure relationship.
