Allmand Bros. Inc., a subsidiary of Briggs & Stratton Corporation and long-time manufacturer of high-performance portable equipment, expands its product offerings into the portable air compressor market. The Maxi-Air™ Portable Air Compressor’s heavy-duty, over-sized rotary screw air end provides consistent, high-pressure air volumes at low rpm for enhanced fuel efficiency. The Maxi-Air comes in two models, the MA185 and MA400, with free air delivery of 185 scfm and 400 scfm, respectively. Both models achieve a maximum working pressure of 120 psi.

“The Maxi-Air portable air compressors are designed for maximum performance,” said Brian Northway, product manager, Allmand. “Like all Allmand products, reliability was our top priority in developing this line. Both units are built to last and designed for fast and easy maintenance as well as long service intervals.” 

Maxi-Air compressors incorporate features for easy starting and quiet use. A high-capacity cold start battery increases cold-cranking amperage to ensure easy starting in any weather. Two 3/4-inch Chicago-style fittings enhance usability by providing high air output. And sound-attenuated airflow reduces operating noise to a mere 63 decibels — about the same level as a human voice. 

Both units are designed with a focus on uptime. A large-capacity fuel tank only requires fueling once every 8 hours for maximum productivity. Should the compressor run out of diesel, an electric fuel primer and air-bleed (EFPA) pump allow for easy restarting without requiring service for priming.

The compressors include numerous features that enhance convenience and lessen maintenance time. All fluids are plumbed to the curbside edge of the enclosure for easy maintenance access. Additionally, both units feature an externally mounted water separator filter and a conveniently positioned radiator for easy accessibility. Also, the fiber gear coupler requires no maintenance.

Beyond easy use and maintenance, the Maxi-Air compressors’ rugged design ensures years of use. A heavy-duty steel enclosure with powder-coat paint and stainless steel hardware resists corrosion in the harshest environments. Even the frame of the undercarriage features powder-coat paint protection to stand up to tough jobsite conditions.

The need for convenient portability also factors heavily into the design, from the long-wear 15-inch tires to the adjustable coupler channel that allows the operator to tow the trailer level to the ground.

The MA185 runs on a 48-horsepower Tier 4 Final Yanmar engine and delivers 185 scfm. It consumes just 2.4 gallons of fuel per hour at full load capacity and features a 24-gallon tank. It has an operating weight of 2,450 pounds and uses a 12-volt electrical system. Canadian customers also have the option of the 400-scfm MA400, which runs on a Tier 3 Isuzu engine, weighs 5,000 pounds and has a 24-volt electrical system.
