Introduction de produit

This smallest retained cabinet tempers replacement air for systems exhausting between 800 and 3200 CFM. Its approximately 700 lb configured mass and 39 x 33.7 inch face make it practical for a local utility or laboratory exhaust system that does not need a large central makeup-air plant.

Key Features

Local exhaust replacement

The airflow range matches smaller extraction systems without forcing a large unit to operate at the bottom of its capacity.

Compact burner package

Direct-fired heating tempers cold outdoor air within a short cabinet arrangement.

Defined small-unit weight

An approximate 700 lb configured weight supports roof curb or housekeeping-pad selection.

Solutions for Your Application

Unconditioned replacement air causes winter drafts and room pressure instability.Match the supply airflow to the exhaust rate and modulate the direct-fired heating section to the required discharge condition.

A central-size unit would be too heavy and difficult to turn down for the local system.Use the compact 800-3200 CFM platform close to its intended operating band.

Options disponibles

Gas train, burner modulation, intake hood, filter section, discharge orientation, fan controls and roof-curb arrangement can be selected.
