We manufacture a comprehensive range of compact, self-contained air compressors suitable for dry, pre-action, alternate or tail-end sprinkler systems. All of our compressors are designed to comply with LPC, EN12845 and PED guidelines and are fully set and tested prior to despatch.

Our compressors are manufactured with or without air receivers, or for low-pressure applications; numerous options and variations are available to order to solve any problem – something which most of the competition would struggle to do.

We manufacture our unique duplex compressor stations for a number of reasons; the need for resilience/redundancy; additional capacity in the absence of three-phase supply, space-saving etc.

A duplex station (automatically or manually controlled to allow coincident and/or alternate use of compressor pumps) can be manufactured using virtually any of the compressors in our range and for either 230v or 400v supplies.

Our recommended desiccant dryers are designed to provide a controlled supply of ultra dry, ultra clean compressed air to dry pipe systems where freezing is possible. Typical installations include within commercial freezers, unheated warehouses, exposed loading docks etc.

These dryers (preceded by an oil removal filter) can be used with any of our receiver model compressors.

As a major buyer of compressors, SEP has access to most European manufacturers’ ‘off the shelf’ ranges at beneficial prices, and we can therefore offer you the best solution to your Industrial, Professional and Automotive requirements.

Our selection, sourced for customer service, fast response, quality, reliability and efficiency includes (but is certainly not limited to!) Nuair, Fini, ABAC, Bambi, Fiac and Kaeser.

We manufacture quite a variety of Air Maintenance Devices, often used for sprinkler systems that run off the works main air supply, or a separate compressor with air receiver, to automatically control air entering the system at the required pressure.

The regulated air supply is directed through an orifice plate in ‘top-up’ mode, or there is a full-bore bypass for ‘refill’ mode.

SEP now offers a range of highly cost-effective compressed air regulators, and combined filter/regulators for use with air compressors on pre-action dry, alternate or tail-end systems.

Our regulators conform to ISO6953-1 and incorporate a press-to-lock adjuster with a highly visible red band if they are not locked.
