Specialist air compressors have been the backbone of SEP since its inception over 30 years ago. 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 as many LPC, EN12845, and FM Approvals guidelines as possible, latest PED regulations, are both CE- and UKCA-marked, and are of course fully tested and factory set prior to despatch. As required for FM systems, and where you are using an air maintenance device or regulator, models with air receivers (minimum 24 litre) are available.
Our compressors are built and tested to exacting standards for quality, reliability and longevity; cheaper compressors are available from others.
Please go to our ‘Downloads’ page for more detailed data sheets, O&M documentation and our easy-reference notes on LPC and FM guidelines.
Key Features
- Standard: Danfoss pressure switch set ~2.5-3.5 bar (minimum differential 0.8 bar).
- Low pressure upgrade: for cut-out below 2.5 bar or differential between 0.15-0.8 bar.
- Pressure safety relief valve to suit factory set pressure.
- Glycerine filled 63mm pressure gauge.
- Contactor starter with thermal overload electrical protection.
- Unloader valve and non-return valve prevents compressor starting under load.
- On-delay timer (400v models require neutral for a 230v supply) to prevent immediate cut-in in the event of sprinkler activation, reduce the number of starts and promote longevity.
- 0.5m flexible hose (1m available) with ½” adaptor for system connection.
- Integrated brackets for wall-mounting (floor-mounting kits available).
- Hard-wearing powder coated frame in our trademark silver hammer.
- Air receiver models include 24 litre receiver with manual drain valve (auto-drain option available).
- New for 2021: ultra-quiet oil-free, just 58dB(A)!
