STjh longest 16 by 48 inch reverse-flow HEPA unit with 4.5 square foot intake and full dust pan

STJH-NEGATIVE-PRESSURE-HEPA-UNIT-16X48

Negative-Pressure HEPA Filtration Unit 16 × 48 in

The longest narrow reverse-flow model, providing a 4.5 ft² HEPA collection face for broad exhaust zones.

47.63 in long chassis
4.5 ft² active filter face
Narrow negative-pressure pickup

Introduction de produit

The 16 x 48 in configuration maximizes capture length within the narrow reverse-flow family. Its 4.5 ft² active filter face spans a 47.63 in cabinet depth while keeping the housing width to 15.7 in. A backward-curved variable-speed PSC blower draws room air through the MERV 7 and HEPA stages for broad isolation or powder-containment coverage.

Key Features

Broad linear collection

The 48 in length distributes exhaust pickup along a long work or maintenance zone.

Room-side dust control

A collector pan sits beneath the accessible filter path for service within the enclosure.

Ductless ceiling integration

The reverse-flow chassis can operate as a ceiling module without a separate downstream duct section.

Applications

Used over long isolation enclosures, broad repair bays and controlled powder-handling zones. The extended pickup can reduce the number of small exhaust modules when ceiling geometry permits one long unit.

Solutions for Your Application

Multiple short exhaust points create uneven collection along a long enclosure.Apply the continuous 4.5 ft² filter face across the principal contaminant-release line.

A long suspended cabinet may conflict with ceiling supports.Map the 47.63 in body against the support grid and use dedicated suspension points where required.

Options disponibles

Select surface frame, inlet adapter, filter alarm, suspension kit and fan controller. Electrical data and final duty should be established for the installed filter resistance.
