Safe and customizable, the Radial-Tip Belt-Drive industrial fans are used for make-up air and general ventilation duty. They can also serve as components in dust collection and cyclone receiver systems. Available with pedestal or unitary bases, the fans can generate flowrates from 1,000 ft3/min to 100,000 ft3/min. The wheels are statically and dynamically balanced for smooth running and the V-belt drive allows fine-tuning of fan speed and flowrate by changing pulleys and belts.

Suitable for use in explosive and caustic environments, these rotary air-powered explosionproof fans eliminate expensive magnetic starters and heavy hardwall conduit lines. Approximately 70% lighter than comparable belt-driven fans, these easy-to-install units feature flanged housings, permitting quick fastening to flexible duct or other accessories. Adjustable turbo-vane air motors operate in any mounting position and cannot be overloaded. These streamlined motors limit fan housings to a depth of 12–15 in.

Custom-built to suit specific job and application requirements, Omega-paK rotary-lobe blower packages are delivered factory-assembled and ready-to-install. The blower packages are comprised of two-lobe Omega blowers and a premium efficiency motor, pre-mounted on a sturdy frame with inlet and discharge silencers. They feature a pivoting motor base and tension spring that automatically applies the correct V-belt tension to maximize transmission efficiency. A visual indicator prevents overtensioning to extend belt, pulley and bearing life.

Combining the efficiency of centrifugal airfoil wheels with the versatility and compactness of an axial-flow fan design, Tubular AcoustaFoil fans provide quiet operation for clean-air applications. Suitable to accommodate capacity needs up to 140,000 ft3/min, these fans operate at efficiencies beyond 75% in pressures up to 14-in. H20 (gauge). Their heavy-gauge welded components deliver structural strength and durability with minimal leakage. Available in 16 sizes of wheel diameters ranging from 12 in.

Designed to handle static pressures up to 4-in. H20 (gauge), the high pressure TA-HP tube axial fan is made of fiber-reinforced plastic. Direct and belt-driven fans feature helical-shaped blades that process up to 90,000 ft3/min. With wheels made from vinyl ester resin and housings from polyester resin, these flame-resistant fans are able to withstand corrosive environments.

The Cheminert Model M6 and M50 liquid handling pumps are designed for precision handling of liquids and/or gases, and produce a bidirectional pulseless flow with a range over six orders of magnitude, from 10 nL/min to 10 mL/min for the M6 pump, and 50 µL/min to 50 mL/min for the M50 pump. Positive-displacement pumps offer much better performance than syringe pumps, which need refilling and syringe changes. They are self-priming and tolerant of any gas that may find its way into the fluid lines. There is no separate fill cycle, and the capacity is virtually unlimited.

PDCL Series positive-displacement liquid flow calibrators cover flows ranging from 0.01 gal/min (0.04 L/min) to 400 gal/min (1,514 L/min) with an uncertainty of ±0.05% and a repeatability of 0.01% of reading. These volumetric devices displace an exact known volume of fluid, which passes through the flowmeter under test while compensating for fluid viscosity and temperature. They perform NIST-traceable calibrations of common flowmeters, including turbine, differential-pressure orifice plate, rotameter, variable area, coriolis, and any other type with a visual, pulse or analog output.

This chemical treatment system accurately meters caustic soda and other pH-adjusting chemicals for water and wastewater treatment applications. Since well water is typically acidic and damaging to distribution piping, the water’s pH needs to be raised.

These custom die-cut polytetrafluroethylene (PTFE) gaskets are fabricated for a precise fit and are available in sizes from 0.25 in. to 60 in. dia. by 0.003 in. to 0.250 in. thick. They are chemically inert and unaffected by most corrosive liquids, vapors, and gases. The gaskets are made from virgin or filled PTFE, paraformaldehyde (PFA), thermally fused melamine (TFM), or expanded PTFE. The properties of these materials make the gaskets suitable for applications requiring durability and slipperiness.

The Liquid Flow Controller doses small volumes at (nominal) flowrates of 10–600 mL/min (0.6–36 L/h) with a 1:10 measuring span. It performs the dynamic control or metering of liquids and is suitable for a variety of industrial applications, including heat treatment, testing, surface-coating, filling, and packaging. When combined with the manufacturer’s mass flow controller, it can simultaneously meter gases and liquids in atomizing and sterilization processes.
