Power consumption Temperature rise 4 W type 5C 10 W type 14C Required time for attachment/detachment: Approx. 5 seconds (per unit) Reduces installation time for multiple numbers of valves. During continuous operation at 24 VDC, 0.25 MPa, 300 Hz Filter is mounted to port 1 (IN). Filter is mounted to port 1 (IN) for quick disconnect type as well.

Take measures to prevent freezing, since moisture in circuits can freeze under 5C, and this may cause damage to seals and lead to malfunction. Refer to the "Air Cleaning Equipment" catalog for details on compressed air quality. Caution 1. Drain flushing Remove drainage from air filters regularly. 19 Series MLGP Auto Switch Precautions 1 Be sure to read before handling.

In addition, the cooling water cannot theoretically be cooled to a temperature any lower than 5C above the wet-bulb temperature of the outside air.
Take measures to prevent freezing, since moisture in circuits will be frozen under 5C, and this may cause damage to seals and lead to malfunction. Refer to SMC's Best Pneumatics catalog vol. 4 for further details on compressed air quality. 4. Take measures to prevent possible fluctuations in pressure.
