Features
● Energy saving type vacuum pump, air consumption reduces 90% (comparing with non-energy saving type), vacuum
digital pressure switch with energy saving function, stop air supplying when preset vacuum value reaches.
● Efficiency fo vacuum pump increases (compared with single stage vacuum pump), vacuum flow increases 50%, air
consumption reduces 30%.
● Small and light.Volume is 85cm3, weight is 90g.
● Saving lines (D type auxiliary plug), saving work time for tubing, wiring and setting.
● Transparent housing, easy to indicate degree of contamination and disassemble and clean.
● Various mounting ways, bracket for single body, DIN guide rail for both single body and combined type.
How to order
AZK - S × 8 - J - N - D
① ② ③ ④ ⑤ ⑥
① Series | ② Specification | ③ Stack | ④ Supply valve and release valve | ⑤ Vacuum switch | ⑥ Bracket |
AZK | S - Low vacuum level type X - High vacuum level type P - Low air supply pressure and high vacuum level type D - Pollution proof type L - Large flow type | Nil - Single body 2 3 …
8 | Nil - Supply valve NC+ release valve NC J - Supply valve NC, without release valve NO - Supply valve NO+ release valve NC (lead wire length 300 mm, power supply DC24V) | Nil - Without vacuum switch N - NPN,without energy saving function P - PNP,without energy saving function NE - NPN,with energy saving function PE - PNP,with energy saving function | Nil - Without bracket F - With bracket (single body) D - With guide rail |
Remark:1. Only NE/PE with check valve, for pressure maintaining. Others without check valve.
2. NE/PE do not apply to L- Large flow type.
3. NE/PE do not apply to J type-with supply valve NC but without release valve.
