The M81 offers variable pressures for increased performance and flexibility on site.
The new M81 is the latest heavy-duty portable compressor in our popular MOBILAIR™ line. This versatile unit delivers up to 295 cfm at 100 psig, and is designed for civil and commercial construction, demolition, sand-blasting, fiber optic cable blowing and other utility applications.
The MOBILAIR M81 is available with an adjustable pressure range of 100 to 150 psig, and also 100 to 200 psig. Its innovative pV control system automatically increases free air delivery when a lower operating pressure is selected, optimizing energy efficiency, and ensuring air supply is precisely matched to demand.
The M81 is designed for durability and efficiency in all environments. A reliable Hatz diesel engine meets US Tier 4 Final specifications and provides 11 hours of consistent, high performance operation with the lowest possible emissions. The anti-frost control automatically adjusts operating temperature based on ambient conditions, and along with the optional tool lubricator, protects tools from freezing. The wide-opening, scratch and dent resistant, molded polymer gull wing doors provide all-weather protection and easy access to maintenance points. Plus, the standard Sigma Control Smart with its easy-to-use menu display allows the user to adjust settings as well as monitor fuel consumption, fluid levels, and operating conditions.
