The Stockpile · Pile 01 — The Services
Filter change-outs, pulse repairs, leak detection and full rebuilds — most major brands.
Complete care for baghouses and cartridge collectors: filter change-outs, cages, pulse system repair (solenoids, diaphragm valves, timer boards), leak detection, DP diagnostics, hopper discharge repairs, and full rebuilds of tired collectors. We service most major brands — Camfil Farr, Donaldson Torit, Imperial Systems, Nederman and more — and stock the wear parts in Fontana.
Differential pressure is the collector’s vital sign. If nobody trends it, the first symptom you notice is the expensive one. Ask about DP monitoring on your next service visit.
Housings outlast their internals. New bags and cages, a rebuilt pulse system and corrected ductwork often bring a collector back to spec for a fraction of replacement cost. When replacement genuinely wins, we say so — and handle the complete installation, ductwork and support steel with our own crews.
| Symptom | Likely cause | Fix |
|---|---|---|
| High differential pressure | Blinded bags, failed pulse cleaning, or moisture in the housing | Check pulse valves and air quality first; media may be recoverable |
| DP near zero | Broken bags or bags off their cages — air is bypassing the media | Inspect and replace; find what tore them |
| Visible stack emission | Leaking bags, failed snapband seats, or tubesheet cracks | Leak-locate (fluorescent powder), reseat or replace |
| One row pulsing weak or leaking | Failed pulse valve or diaphragm on that header | Valve rebuild — then check the bags it starved |
| Hopper bridging with dust | Dust being stored, not discharged | Fix the discharge — hoppers are funnels, not bins |
| Bags dying young | Wrong media for temp/moisture/abrasion, or cage damage | Media review — see the air filters section for the selection table |
Filter bags, cages, bag clamps, venturis, air solenoids and repair kits, diaphragm valves, timers, gauges, vibration sleeves and controls — for major collector brands, on shelves in Fontana.
Years, in a properly sized and maintained collector. Bags dying in months means an operating or design problem — worth diagnosing before the next change-out, not after.
Yes — see our explosion protection service for NFPA reviews, venting and isolation. If your dust has never been tested for combustibility, start there.
Reading about it is free. So is the phone call. Some answers only come from climbing into the equipment — that’s the part we do in person. Tell us the plant, the part and the problem, and you’ll get a real person.
