HOW TO ORDERVU-18F

VACUSTATThe Vacustat is the basis for energy-saver controls and is used with any suitable vacuum pump in conjunction with a vacuum check valve. Vacuum pumps that are equipped with an integral non-return valve or a vacuum pump and external vacuum check valve such as VC18 fit the requirements for a vacustat control. As always, energy-saver controls can only be used in leak-free systems and some provision must be made to dissipate the checked vacuum and release the work piece when desired.

VU-18F is an adjustable vacuum-controlled 2/2 valve that supplies compressed air to the vacuum pump whenever system vacuum level is shallower than the Vacustat set point. When the set point is achieved, the Vacustat shuts off the pump air supply until system vacuum level again requires replenishment.

Electrical pressure sensors come with UL and CSA snap action silver contact SPDT (Single Pole Double Throw) switch with 0.187in (4.75mm) spade terminals. Triple terminal electrical connector and insulator kit for attaching wires is included.

Pneumatic pressure sensors are available in normally-closed (NCL) and normally-open (NOP) versions. Normally-closed (NCL) sensors open to pass air when the desired set point is achieved. Normally-open sensors close to block air when the desired set point is achieved. Both versions have integral 5/32 (4mm) tube connectors.

The rugged F10-18F inline filter is designed to carry the full load of 50mm and smaller suction cups. The inline filter is ideal for use with Flow Sensor or Tri-Flow Valves in extremely dusty environments such as woodworking shops. The F10-18F provides more than 10 times the surface area of the standard FSV filter disk, providing a longer life. A Quick Release (blow-off) may be used to momentarily back flow the filters to help keep them clean.

VSP-18 - Bi-directional VSP protects vacuum switches or gauges from positive pressure spikes byrelieving pressure in excess of 10 psi (0.7 bar) to atmosphere. Connects to 1/8” NPTF or1/8” BSPP threads.

Some sizes are available in polypropylene. Call for availability. Add suffix - PP for polypropylene body and bowl. Bowl will be opaque, NOT transparent. For example: PPSF750X35-PP would be a 3/4 NPTF filter made of Black polypropylene.
