CDHR Series Cartridge Dust Collector Pulse Jet Cartridge Type Dust Collector For Welding Fume & Metal Working Dust

Product Overview

For discrete workshop dust‑producing points such as welding stations and grinding workbenches, cartridge dust collector is a mature modular dust‑removal solution. This CDHR series equipment belongs to the product range under Air Cleaning product catalogue. It runs under negative‑pressure working condition; dust‑laden gas enters the tank body, solid particulates are trapped on the outer surface of pleated filter cartridges, and clean air is discharged outward. When filter‑element resistance rises to preset threshold value, pulse valves eject compressed air to blow off accumulated dust on cartridge surface automatically, without halting whole‑machine operation. It features compact footprint, easy on‑site assembly, and is widely deployed for metal processing, welding smoke treatment, abrasive blasting workshop and paint‑spraying booth dust control.

Basic Technical Parameters

Typical On‑site Application Scenarios

This CDHR cartridge dust collector is highly suitable for scattered dust sources inside manufacturing workshops. In automobile welding workshops, it captures a large amount of welding fume produced during spot‑welding operations to improve workshop air quality. Abrasive blasting workshops use it to intercept steel‑sand and oxide‑scale dust generated during workpiece surface treatment. Small‑scale paint‑spray workshops adopt CDHR equipment for dry‑type paint mist particle interception. It can also match dust filter cartridge with different filter media according to dust properties, including cellulose and polyester media for different dust‑load requirements. Different from large‑volume baghouse dust collectors, CDHR modular units can be flexibly expanded according to actual dust‑producing points quantity on‑site.

Core Product Advantages

Modular combined design greatly reduces on‑site welding and installation workload; modules can be loaded directly into standard shipping containers to cut overseas transportation cost. Pulse‑jet automatic cleaning supports continuous long‑time running, manual frequent disassembly cleaning is not required. The maximum whole‑machine operating resistance is controlled within 1500Pa, lowering fan power consumption and operating cost. Quick‑open access doors facilitate later‑stage dust filter cartridge replacement work without special hoisting tools. Multiple optional filter‑media adapt dry fine dust, oily fume and other complex workshop dust conditions.

Manufacturer & Factory Strength

Xinxiang Lifeierte Filter Corp.,Ltd (Stock Code:837936) completes the whole‑machine structural design, sheet‑metal welding, pulse‑valve matching and complete‑machine performance testing in‑house. Each CDHR dust collector will pass air‑tightness inspection and full‑cycle pulse cleaning functional test before leaving factory. We can adjust module quantity and internal filter‑element configuration for customers’ actual air‑volume demand. Besides dust‑removal complete equipment, we also supply full‑range of spare industrial air filter consumables for long‑term after‑sales maintenance.

FAQ

Q1：What kind of dust is CDHR cartridge dust collector suitable for?
A1：It is mainly applicable for dry particulate dust such as welding fume, grinding metal dust, paint‑spray dry dust, blasting‑sand dust; it is not suitable for high‑humidity sticky dust which is easy to paste on filter‑element surface.

Q2：Can CDHR series realize differential‑pressure automatic pulse cleaning?
A2：Yes, it supports two trigger modes: fixed‑time timing cleaning and differential‑pressure threshold trigger automatic cleaning, users can switch according to site dust‑concentration condition.

Q3：What filter‑media options can be selected for CDHR filter cartridges?
A3：Cellulose media, cellulose‑polyester blended media, flame‑retardant treated media are optional, we will recommend suitable media according to dust composition.

Q4：Does CDHR equipment need complex foundation construction when installing?
A4：Standard‑type CDHR modular dust collector can be placed on flat cement ground, no special civil‑engineering foundation is required under most working‑conditions.

Q5：Do you supply spare pulse valves and differential‑pressure gauges as separate spare‑parts?
A5：We provide complete supporting spare‑parts including pulse valve, differential‑pressure gauge, filter‑cartridge and controller components for daily site maintenance.
