- (Note 1)Do not use corrosive gas because there is possibility that the pump breaks down by the product material.
- (Note 2)mL/min: volume flow rate at 0 degrees C., 1 atm (Compatible with SCCM).
- (Note 3)The maximum allowable flow rate depends on the gas type, the APC valve temperature, the gas purge flow rate and outlet pressure.
- (Note 4)Without a protective net. Pumping speed for N2 is 2550 L/s with a protective net.
