Allegro 9832-S 3-man Portable Sar Air Compressor

Product Description

The ALLEGRO 9832-S is a portable supplied-air respirator (SAR) compressor designed to deliver clean, breathable air to up to three workers simultaneously via Schrader coupling connections. Rated at 20 CFM at 60 Hz and 1.5 HP, this unit provides enough airflow capacity for three-man crew operations in confined spaces, spray finishing environments, and other atmospheres immediately dangerous to life or health (IDLH). With a maximum operating pressure of 15 psi, it delivers low-pressure grade-D quality air through standard SAR hose assemblies. This compressor is installed and serviced by industrial hygienists, safety professionals, and licensed contractors who manage respiratory protection programs on job sites.

The 9832-S is suited for industrial and commercial applications where ambient air cannot be safely used for respiratory protection. Typical deployment includes confined space entry, abrasive blasting support, painting and coating operations, and hazardous material remediation. The Schrader coupling interface provides compatibility with standard SAR hose manifolds and distribution systems. This unit supports simultaneous three-worker supplied-air operations without requiring a separate air cylinder or cascade system.

Key Features

• Supports up to 3-man simultaneous SAR connections via Schrader couplings
• 20 CFM airflow rating at 60 Hz provides adequate volume for three-person crew supplied-air respirator use
• 1.5 HP motor drives portable, job-site-ready operation
• 15 psi maximum pressure matches low-pressure SAR system requirements
• Portable design allows repositioning between work areas and job sites
• Filtration panel and hose not included — pairs with separately sourced SAR distribution components

Compatibility

Designed for use with standard low-pressure supplied-air respirator systems using Schrader coupling connections; supports up to three simultaneous worker connections. Filtration panel and hose assembly are not included and must be sourced separately for compliant SAR operation.

Installation Notes

Installation and commissioning of supplied-air respirator compressors must be performed by qualified personnel familiar with OSHA 29 CFR 1910.134 respiratory protection standards and the compressor manufacturer specifications. Ensure the air intake is located in a clean-air zone free of combustion exhaust, solvent vapors, and other contaminants before startup. All SAR distribution hoses and couplings should be inspected for leaks and rated for the operating pressure before connecting workers. Do not exceed the 15 psi maximum rated outlet pressure.
