Overview

Sandblasting machine dust collector high-efficiency dust removal filter cartridge 350 * 660 single pass double pass. Most sandblasting machine dust collectors are fixed at one end, and single pass installation and sealing are more reliable, with lower operation and maintenance costs; Only select dual pass when the device is clearly designated as dual end fixed/dual pass airflow.

Product Details

Sandblasting machine dust collector efficient dust removal filter cartridge 350 * 660 single pass double pass

350 × 660 (outer diameter 350mm × length 660mm) is the mainstream filter cartridge specification for the pulse dust collector of the sandblasting machine. The core difference between single pass/double pass is the airflow path, installation, fixation, and sealing. The filter material and filtration efficiency can be kept consistent (PTFE coated version ≥ 99.99% @ 0.3 μ m), and the selection needs to match the dust collector flower plate and airflow direction.

Single pass vs dual pass core comparison (sandblasting machine working condition adaptation)

dimension	Single pass (one end open/one end closed)	Double pass (open at both ends)
Airflow path	External → Internal → Single end discharge; Pulse blowback from inside to outside	One end enters → outside → inside → the other end exits; Reverse blowing in the opposite direction
Installation/sealing	Single end fixed (six ear/screw), with fewer sealing points, more stable in preventing bypass leakage; Quick disassembly and assembly	Both ends must be fixed and sealed, and the flower board and end cover must be compatible; Disassembly and assembly is slightly complicated
Structure/Strength	Built in support skeleton, resistant to reverse blowing deformation; Adding external network makes it more resistant to sand impact	Supported at both ends, with more stable pleats; Suitable for long filter cartridges and high wind speeds
Applicable scenarios	Mainstream sandblasting machine pulse dust collector, flower board single end layout; Priority selection	Large array, fixed at both ends, high wind speed/high concentration; Need to confirm equipment structure
Cost/Operations	Low unit price and sealing component cost, fast replacement and short downtime	The unit price and sealing component cost are slightly higher, and the replacement time is slightly longer

Key Decision Points for Selection of Sandblasting Machine Operating Conditions

First check the equipment drawings/nameplates📐： Confirm the opening, interface size (commonly ≈ 240mm), airflow direction, and fixing method of the flower board to avoid installation failure.
PTFE coated PET is preferred as the filter material🛡️： Surface filtration, easy to clean dust, and resistant to sand abrasion; Flammable and explosive dust such as aluminum magnesium powder/metal sand must be selected with anti-static filter materials and grounded outer mesh/skeleton to suppress static electricity accumulation.
Adding an external network makes it more durable⚙️： Carbon steel galvanized/stainless steel diamond mesh (with an opening rate of ≥ 50%), which prevents sand particles from directly impacting the filter material and extends its service life.
Temperature and pressure🌡️： Conventional ≤ 85 ℃; High temperature version ≤ 100 ℃; Compressed air blowback pressure is 0.3-0.5MPa to avoid excessive blowback and fatigue of the filter material.
Single pass priority principle✅： Most sandblasting machine dust collectors are fixed at one end, which makes single pass installation and sealing more reliable and has lower maintenance costs; Only select dual pass when the device is clearly designated as dual end fixed/dual pass airflow.

Installation and maintenance tips

Sealing: When replacing, check that the sealing ring (chloroprene/fluororubber) is intact, and ensure that there is no bypass leakage after installation.
Dust cleaning: Set a reasonable pulse period and width to maintain stable pressure difference; Clean or replace the dust promptly when the pressure difference rises abnormally.
Anti static: Reliable grounding, regularly check the grounding resistance to avoid the risk of sparks.
External network: Regularly check for deformation and rust, and replace damaged parts in a timely manner.
