Bifold Air Preparation Equipment

Air Preparation

Air preparation equipment is designed to provide top-quality air supply to compressed air systems. If dirty or wet air is processed through a system it can cause issues, including downtime and failure of other equipment downstream.

At MGA Controls, we supply a comprehensive range of Bifold air preparation equipment including the Bifold SC and SH compact air preparation unit range. Bifold air preparation equipment is well-known for its use in an array of industries, including oil and gas, offshore, chemical and refinery.

Bifold SH and SC units
