Matsubara Iron Works Ltd. was established in 1904, and manufactured semi-diesel marine engines, clutches and chain blocks.

In 1941 they started developing high pressure air compressors. Through their long history over 100 years, they have got rich experience and excellent technique. Therefore, it is used nationwide as a diesel engine starting air compressor for medium and small ships, the accumulated number already shipped is over 50,000 units, and domestic shipping vessels occupy more than 40% share.

As it is now, air compressors are in their delighted main line. They are ranging 2.1-29.4kW and working on cargo boats, passenger's, patrol's, tankers, fishing boats and land power pants.

Additionally, air respirator air compressors (15 MPa to 30 MPa) are used for onshore respirators for scuba diving and fishing, fire department, police and Self-Defense Forces for fire fighting activities and life saving activities.
