Our Product development team created a limited number of the MV-89G portable twin cylinder air compressors enclosed in an actual US. Military surplus Pelican Model 1520 case by PSI. The MV-89G is a powerhouse, portable compressed air unit, capable of inflating a 37” tire from 10 to 35psi in 2:20 seconds. The cases were originally used to protect delicate medical electronics in the field. Lightweight, waterproof and almost impossible to break - all it took were some internal modifications and the MV-89G fit nicely inside. Also included is the original MV-89G compressor carry bag in the event you find another use for this great protective case. The photos show the modified interior as well as the authenticity of the case for your reference.
