Air fuses Throughout industrial automation, extensive use is made of flexible hoses used to connect together two or more portable devices. Should this hose fail in service either via damage or excessive wear, then escaping air can create a major hazard to personal safety. A simple air fuse, correctly installed, can provide an effective anti-flay device should failure occur. Following repair of the hose, the airfuse resets automatically for subsequent use. > Tamper-proof - requires no adjustment > Number of options of size and flow capacity > Minimal pressure drop across device Tamper-proof pressure regulator Health and safety guidelines require simple blow guns – used throughout industry – to be supplied with a maximum pressure of 2 bar for reasons of safety. The easiest way of ensuring that this happens is to use a IMI Norgren preset tamper-proof regulator from the R16 range. This unit is factory set and locked prior to despatch. On applications using flexible hoses, the R16 should also be used in conjunction with an air fuse, shown above. > Compact and easy to install > Cannot be tampered with by operators > Available with different pressure settings for use on other applications anti-flay protection Model Description Port Size Reduced Pressure At Shut Off Flow Rate Required To Achieve Shut Off * T60C2890 Low Flow Air Fuse G1/4 0.14 bar 500 l/min T60C3890 Low Flow Air Fuse G3/8 0.14 bar 1,160 l/min T60C4890 Low Flow Air Fuse G1/2 0.14 bar 1,930 l/min T60C6890 Low Flow Air Fuse G3/4 0.14 bar 2,900 l/min T60C8890 Low Flow Air Fuse G1 0.14 bar 5,520 l/min T60CB890 Low Flow Air Fuse G1 1/2 0.14 bar 11,160 l/min T60C2891 High Flow Air Fuse G1/4 0.30 bar 840 l/min T60C3891 High Flow Air Fuse G3/8 0.30 bar 1,930 l/min T60C4891 High Flow Air Fuse G1/2 0.30 bar 2,900 l/min T60C6891 High Flow Air Fuse G3/4 0.30 bar 4,800 l/min T60C8891 High Flow Air Fuse G1 0.30 bar 7,680 l/min T60CB891 High Flow Air Fuse G1 1/2 0.30 bar 16,080 l/min T60A2890 Low Flow Air Fuse 1/4 NPT 2.0 psig 18 scfm T60A3890 Low Flow Air Fuse 3/8 NPT 2.0 psig 41 scfm T60A4890 Low Flow Air Fuse 1/2 NPT 2.0 psig 68 scfm T60A6890 Low Flow Air Fuse 3/4 NPT 2.0 psig 102 scfm T60A8890 Low Flow Air Fuse 1 NPT 2.0 psig 195 scfm T60AB890 Low Flow Air Fuse 1 1/2 NPT 2.0 psig 394 scfm T60A2891 High Flow Air Fuse 1/4 NPT 4.4 psig 30 scfm T60A3891 High Flow Air Fuse 3/8 NPT 4.4 psig 68 scfm T60A4891 High Flow Air Fuse 1/2 NPT 4.4 psig 102 scfm T60A6891 High Flow Air Fuse 3/4 NPT 4.4 psig 170 scfm T60A8891 High Flow Air Fuse 1 NPT 4.4 psig 271 scfm T60AB891 High Flow Air Fuse 1 1/2 NPT 4.4 psig 568 scfm * At 7 bar supply pressure ± 10% Model Description Port Size Preset Pressure Flow Rate R16-200-R30G Pre-set Pressure Regulator G1/4 2 bar 340 l/min R16-200-R30A Pre-set Pressure Regulator 1/4 PTF 30 psig 12 scfm Other models available contact IMI Precision Engineering for more information Preset SAFE SYSTEMS 09
