Ring Main Systems
Ring main systems provide a reliable and efficient way to distribute compressed air throughout workshops, garages, and industrial environments. By allowing air to flow from multiple directions, ring mains reduce pressure drop and deliver consistent air supply to every outlet.
Modern ring main systems are designed for fast installation, clean layouts, and easy future expansion, making them suitable for both new installations and retrofit projects. They are widely used in automotive workshops, MOT centres, and industrial facilities where reliability and performance are essential.
Ring main system options include lightweight aluminium modular systems such as Transair and Prevost PPS1, cost-effective plastic systems including ABS and uPVC, and traditional malleable iron systems for threaded pipework installations.
Using push-fit fittings for drops or take-offs?
John Guest push-fit airline fittings are commonly used alongside ring main systems for drop lines and quick modifications. They offer a fast, tool-free solution ideal for workshops and garages.
