Products Description
Need a high-efficiency filter element for your vacuum conveying system to prevent product loss? Guanjiang's Vacuum Conveying Filter Elements are specialized filtration components designed for pneumatic conveying systems that transport powders and granular materials through vacuum pressure. These filters serve as the primary separation barrier between the conveyed material and the vacuum pump — preventing product loss while ensuring clean air exhaust. Constructed with pleated filter media in a cylindrical configuration, they feature reinforced support structures to withstand constant pressure differentials (0.2-0.6 bar vacuum) and material impact, with filtration ratings from 1 to 200 microns.
Key Advantages
Prevents Product Loss
High-efficiency filtration prevents product escape into exhaust systems. Minimal product loss during conveying cycles. Protects vacuum pumps from particulate damage.
Reinforced Construction
Withstands constant pressure fluctuations (0.2-0.6 bar vacuum). Reinforced pleat structure prevents collapse under heavy dust loads. Resistant to material abrasion.
Low Pressure Drop
Low pressure drop maintains system efficiency. High dust holding capacity reduces cleaning frequency. Quick cake release during pulse-jet cleaning.
Anti-Static & FDA Options
Anti-static options for explosive dust environments. Fire-retardant media. Compliant with FDA and EU standards for food/pharma.
Long Service Life
Long service life reduces replacement frequency. Efficient cleaning reduces compressed air consumption — minimal maintenance.
Filter Media Options
Polyester / PTFE-coated / Anti-static / High-temperature — select based on application.
Filtration Ratings
1 ~ 200 microns — select based on particle size and product retention requirements.

Selection & Maintenance Guide:
Media selection: Standard polyester for general powders / PTFE-coated for sticky or fine powders / Anti-static for explosive dusts (ATEX) / High-temperature for hot materials up to 150°C.
Filtration rating: 1-10 microns for fine powders / 10-50 microns for standard powders / 50-200 microns for granules and pellets.
Maintenance: Clean using reverse pulse-jet or backflush. Do not use high-pressure water or aggressive solvents unless specified. Replace when pressure drop remains high after cleaning.

Frequently Asked Questions
Q1: How does a vacuum conveying filter element differ from a standard dust collector filter?
A: Vacuum conveying filters operate under negative pressure and withstand constant pressure fluctuations (0.2-0.6 bar). They must prevent product loss while protecting the vacuum pump. Standard dust collector filters operate at lower differential pressures and focus on capturing dust from ambient air, not preventing product escape from a conveying stream. Our filters feature reinforced pleats and support structures specifically for vacuum conveying applications.
Q2: What filtration rating should I choose for my application?
A: 1-10 microns: Fine powders (APIs, milk powder, fine chemicals) — highest efficiency, higher pressure drop. 10-50 microns: Standard powders (flour, resin, pigments). 50-200 microns: Granules, pellets, larger particles — lower pressure drop. Contact us with your material's particle size distribution for a specific recommendation.
Q3: How do you clean the filter element?
A: The filter element is designed for reverse pulse-jet cleaning — compressed air bursts (0.4-0.6 MPa) are fired backwards through the filter, blasting accumulated product off the surface. For non-critical applications, gentle backflushing or vacuuming may be used. Do not wash with water or solvents unless specified (water can damage some media and cause rust on end caps). Replace when pressure drop remains high after cleaning or visible damage occurs.
Q4: When should I use an anti-static filter element?
A: Anti-static filter elements are required for explosive environments where combustible dusts (e.g., organic powders, fine chemicals, food dusts, plastic fines) are present. The anti-static media prevents static charge build-up that could cause sparking and ignition. These filters meet ATEX requirements for Zone 21/22 dust environments. Specify "anti-static" when ordering if you handle combustible materials.
Q5: Are these filter elements FDA compliant for food/pharmaceutical applications?
A: Yes. Standard polyester media is FDA-compliant for food and pharmaceutical applications. For high-purity applications, we offer PTFE-coated or membrane media with FDA approval. Full material certificates (including FDA compliance) are available upon request. Please specify your regulatory requirements when ordering.
