Techcon TSD800-6 1/4 NPT Air Filter

Description

The Techcon air filter mounts inline on the compressed air supply feeding a fluid dispensing system, removing moisture and solid contaminants before they reach the regulator, valve, or dispensing head. Built for a 1/4 NPT female connection, it drops into the air line ahead of TS250 and TS350 series pneumatic dispensers without extra fittings or adapters. The compact housing keeps the footprint small on a crowded bench or cart, and the element services in place, no disconnecting the air line to inspect or replace it.

Where the Techcon Air Filter Fits in a Dispensing Line

Adhesive and sealant dispensing lines run on shop air, and shop air carries condensate, compressor oil carryover, and pipe scale that will find its way into a valve seat or nozzle if nothing stops it first. The filter sits between the air source and the dispenser, catching that contamination before it reaches metering components that depend on clean, dry air to hold a consistent shot size. Moisture carried in the air stream is a particular problem with cyanoacrylates and moisture-cure urethanes, where a damp air supply can trigger premature skinning at the nozzle tip or introduce inconsistency into a metered shot. A 5 micron element also catches the rust scale and pipe debris that a compressor system sheds over years of service, protecting the small internal passages in a dispensing valve or tip that a coarser filter upstream will not stop. It pairs with Techcon TS250/TS255 and TS350/TS355 series digital timed dispensers, the pneumatic systems used to shoot epoxies, silicones, and other fluid adhesives in electronics assembly, potting, and general industrial bonding work. Any bench running one of those dispensers off a shared compressor line benefits from a dedicated filter rather than relying on filtration further upstream, since long runs of air line pick up condensate and rust scale between the compressor and the point of use.

How the Techcon Air Filter Holds Up in Daily Use

The housing handles standard shop air pressure from 20 to 130 psi (1.5 to 9.0 bar) and operating temperatures from -20°C to 70°C (-4°F to 158°F), a wide enough band to sit on an unconditioned shop floor or next to equipment that runs warm during a shift. The element pulls apart without tools and without breaking the air line connection, so a quick visual check or element swap does not turn into a line-disconnect-and-reconnect job. At 425 grams (about 15 ounces), it mounts cleanly on a wall bracket or dispenser stand without adding meaningful weight to the setup.

Specifications

Add this filter to a TS250, TS255, TS350, or TS355 dispensing line as a low-cost safeguard against a fouled valve seat or clogged nozzle, or use it as a direct swap when an existing filter element has reached the end of its service life.
