Controlling Dust During Bulk Loading Starts With the Right Vent Bag

When bulk dry materials are loaded into tanker trucks or rail cars, displaced air carries fine dust out through the vent — creating a worker exposure hazard, an environmental compliance issue, and wasted product. A properly designed vent bag captures that dust at the source, allowing air to escape while retaining the material.

American Fabric Filter manufactures custom vent bags for tanker truck and rail car bulk loading operations across a wide range of industries — grain, feed, flour, chemicals, plastics, minerals, and more. We also manufacture a broad range of other custom products used throughout the transportation and logistics industry, from covers and curtain walls to connector sleeves and specialty fabrications.

  • Custom vent bags for tanker truck and rail car bulk loading
  • Wide range of filter media — felts, wovens, PTFE membrane, anti-static
  • FDA-approved fabrics for food-grade bulk transport applications
  • Custom inlet/outlet sizes, clamp rings, hardware, and attachment styles
  • Replacement vent bags for any make or model of bulk loading equipment
  • Covers, curtains, connector sleeves, and custom fabrications for transport equipment
  • Bulk orders for fleet operations — consistent quality across every unit
Our Core Solutions

Products Built for Transportation & Bulk Logistics Operations

Tanker Truck & Rail Car Vent Bags

Custom vent bags for bulk dry material loading into tanker trucks and rail cars. Captures displaced dust during filling while allowing air to vent freely — available in standard and FDA-approved fabrics for food, chemical, mineral, and agricultural transport applications.

Filter Media & Replacement Vent Bags

Replacement vent bags for any make and model of bulk loading equipment. We match your existing bag dimensions and hardware, or fabricate an upgraded replacement in higher-performance media. PTFE membrane, anti-static, and FDA-approved options available.

Custom Transport Fabrications

Equipment covers, curtain walls, connector sleeves, conveyor catch cloths, and specialty fabric products custom-fabricated for transportation and logistics equipment — any size, any material, built to your specifications and delivery schedule.

Why American Fabric Filter

The Transportation Industry’s
Trusted Filtration Partner

Engineered to Your Exact Specs

Vent bags aren’t one-size-fits-all. Inlet diameter, outlet configuration, hardware type, fabric selection, and overall dimensions all affect performance. We custom-build every bag to your exact equipment and material requirements — no catalog compromises.

FDA-Approved Options for Food-Grade Transport

When you’re loading flour, grain, sugar, or other food-grade bulk materials, your vent bag fabric must be FDA-compliant. We stock and fabricate vent bags in a full range of FDA-approved media to keep your food transport operations compliant.

Bulk Fleet Orders — Consistent Quality

Fleet operators need the same bag to perform the same way across every truck or rail car. We manufacture bulk orders with consistent specifications and quality so your entire fleet stays operational with the same dependable product.

Anti-Static for Combustible Bulk Materials

Loading combustible bulk materials — flour, sugar, grain, plastics — creates static electricity that vent bag media can accumulate. We stock anti-static vent bag fabrics that dissipate this charge, reducing explosion risk and meeting safety compliance requirements for combustible dust handling.

Common Questions About Tanker Vent Bags & Transportation Filtration

What is a vent bag and why is it needed for bulk loading tanker trucks?

When bulk dry material is pneumatically loaded into a tanker truck or rail car, the incoming material displaces an equal volume of air. That displaced air must be vented to the atmosphere — and it carries fine dust with it. A vent bag is a filter mounted to the vent port that allows air to escape freely while capturing the dust before it becomes an environmental release or a worker exposure hazard. Properly designed vent bags protect workers, reduce material loss, and help operations meet environmental compliance requirements.

The right fabric depends on the material being loaded, the flow rate, and whether the application requires FDA-approved or anti-static media. For fine powder materials, PTFE membrane offers excellent dust retention and easy cleaning. For food-grade applications, FDA-approved felt or woven fabrics are required. For combustible materials — flour, grain, plastic powder — anti-static fabric is recommended. We’ll ask about your specific application and recommend the best media.

Yes. Send us your existing vent bag as a sample, or provide the dimensions and hardware style, and we’ll fabricate a direct match. We can also fabricate an upgraded replacement in better-performing media if you want to improve dust retention or extend service life over your current bag.

Yes. We fabricate vent bags for rail car bulk loading in the same range of fabrics and configurations as our tanker truck vent bags. Rail car vent bag requirements often differ in inlet size and attachment hardware — provide us with your equipment specifications and we’ll fabricate accordingly.

Yes. We regularly supply bulk orders of vent bags for fleet operators who need consistent performance across a large number of trucks or rail cars. Bulk orders are fabricated to the same specifications and quality level as single-unit orders. Contact us with your fleet size and change-out frequency to discuss a supply program.
