Replacement Karchers A2004 Wet & Dry Filter – Factory Price?


Factory price Replacement Karchers A2004 Wet & Dry Vacuum Cleaners Cartridge Filter: field-tested notes from the shop floor

If you service small workshops or clean up after messy renovations, you already know a filter can make or break suction. I spent a week rotating filters across two A2004 units and, to be honest, this Factory price Replacement Karchers A2004 Wet & Dry Vacuum Cleaners Cartridge Filter behaved like a no-drama workhorse—no squeals, no leaks, and notably stable airflow.

What’s trending in workshop filtration

Industry-wide, we’re seeing a shift from plain cellulose to resin-reinforced cellulose and PET nano-coated media. The aim is simple: higher dust loading with manageable pressure drop. Shops want fewer swaps, and facilities teams want predictable performance that stands up to wet pickup, too. In fact, many customers say they’ll pay a bit more if the gasket doesn’t compress prematurely and the media pleats don’t glue together after drywall runs.

Where it fits and why it matters

Use the Factory price Replacement Karchers A2004 Wet & Dry Vacuum Cleaners Cartridge Filter for drywall dust, MDF sawdust, concrete fines (dry), and vehicle detailing. It tolerated a surprise wet pickup during testing—still, check your A2004 manual for wet mode; some jobs demand removing or covering the cartridge to avoid media saturation. I guess the key advantage is steadier suction under load, plus a gasket that doesn’t creep after repeated canister twists.

How it’s made (short process flow)

Materials: reinforced cellulose or PET-coated media, steel core, PU potting compound, EVA gasket.
Methods: rotary pleating → end-cap potting → thermal cure (≈60–70°C) → compression-fit gasket → final trim → airflow/pressure drop checks.
Testing: particle efficiency per ISO 29463 principles; vacuum performance per IEC/EN 60312-1 sections on dust pick-up; material screening to RoHS and REACH. Service-life cycling includes dust loading to ∆P threshold and brush-clean recovery.

Vendor snapshot and customization

Origin: Xiangjiang Street South, Jinggangshan Road west, Qinghe County, Xingtai City, Hebei Province. Packaging is, surprisingly, pretty robust—professional, eco-minded, and efficient, which matters for pleat integrity in transit.

Vendor Media/Gasket Filtration class (indicative) Typical price Lead time
Pulongte (this unit) Cellulose/PET, EVA gasket Fine dust ≈ M-range Factory price Stock + custom 2–3 wks
Generic import Cellulose, PU/foam Basic fine dust Low Varies
OEM original Factory spec Factory spec Higher Stable

Customization options: PET nano-coat for sticky dust, PTFE top layer for splash resistance, colored gaskets for fleet ID, and private-label cartons. Honestly, the colored gasket trick saves time in shared shops.

Field notes and small case study

A drywall crew in Hebei ran two A2004 units with the Factory price Replacement Karchers A2004 Wet & Dry Vacuum Cleaners Cartridge Filter for a 3-day patch-and-sand. Suction loss at end-of-day averaged ≈11% vs ≈18% with their prior generic filters, based on airflow readings at the hose cuff. After a brush-out, recovery was near full. Not lab-grade, sure, but good enough for site decisions.

Standards, safety, and care

Follow IEC/EN 60312-1 guidance for vacuum performance checks and use ISO 29463 concepts if you’re bench-testing fine dust. Materials are selected to align with RoHS and REACH. Pro tip: knock-clean gently; don’t blast with 8 bar air directly into pleats. Replace if the gasket hardens or if ∆P grows too fast after cleaning cycles.
