PTFE Aspirators The IPS PTFE Air & Liquid Aspirators are manufactured from virgin PTFE (Teflon® - E.I. Dupont) and are designed for efficient and rapid siphoning of hard to handle chemicals. Our IPS Air Aspirator uses clean dry shop air (CDA) or Nitrogen to initiate and sustain a natural or forced siphon. Applications include the draining and mixing of containment vessels and the removal of saturated waste chemistry. Air Aspirators are also used where recovery recirculation is desired in process chemistries. Our IPS Liquid Aspirators use common city water or DI Water to aspirate and dilute harsh chemical baths. One common application is the dilution siphoning of Sulfuric Acid (H2SO4) used for chemical cleaning and etching. Air & Liquid Aspirators are sold as standalone siphoning bodies or as Aspirator Kits. Kits include 8 feet of PTFE Tubing and Compression Fittings. Our CHK Kit includes a special PTFE check valve mounted on the siphon port to prevent possible back flow. Essentially, an IPS Aspirator is a low cost 100% PTFE Venturi vacuum pump.

Performance Recommendations: • The Minimum Pressure to initiate a siphon is 5 psi. This pressure is a function of the fluid viscosity and ambient conditions. • The 1/2" Aspirator will siphon with a slightly greater vacuum compared to the 3/8" Aspirator. • Overall performance will vary based on the viscoity of the media being siphoned. • Air Aspirators must be mounted at least 14" below the suction point (siphon point). Liquid Aspirators can be mounted level with the suction/siphon point. • For continuous flow applications, it is best to actuate an Air Aspirator with 30 to 50 psi of CDA for...
