Allmand Bros. Inc., a subsidiary of Briggs & Stratton Corp., has expanded its product offerings into the portable air compressor market. The rotary screw air end of the Maxi-Air Portable Air Compressor provides consistent air volumes at low rpm for 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.
Maxi-Air compressors incorporate features for starting ease and quiet use. A 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 63 decibels, about the same level as a human voice.
Both units are designed with a focus on uptime. A large-capacity fuel tank requires fueling once every 8 hours for productivity. Should the compressor run out of diesel, an electric fuel primer and air-bleed (EFPA) pump allow for restarting without requiring service for priming.
The compressors include features that enhance convenience and lessen maintenance time. All fluids are plumbed to the curbside edge of the enclosure for maintenance access. Additionally, both units feature an externally mounted water separator filter and a radiator for accessibility ease. Also, the fiber gear coupler requires no maintenance.
The design of the Maxi-Air compressors ensure years of use. A steel enclosure with powder-coat paint and stainless steel hardware resists corrosion in harsh environments. Even the frame of the undercarriage features powder-coat paint protection to stand up to jobsite conditions.
The need for portability also factors into the design, from the 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 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.
Allmand backs its Maxi-Air portable air compressors with a two-year or 2,000-hour limited warranty. The Yanmar engine includes a five-year or 5,000-hour limited warranty provided by Yanmar, and the Isuzu engine includes a two-year or 2,000-hour limited warranty provided by Isuzu. Allmand also offers an optional air-end five-year or 5,000-hour limited warranty.
