Harbor Freight Dust Collector Bags for Central Machinery
These bags are sized for Harbor Freight Central Machinery 35- and 70-gallon dust collectors. They measure 19.5 inches in diameter (31 inches wide) and 40 inches in length, using a clear, heavy-duty 5-mil plastic. The design focuses on durability and reliability for removing dust and debris from woodshop operations, helping maintain airflow and reduce bag changes.
POWERTEC 70335 Dust Collector Bag
POWERTEC 70335 provides a 1-micron filtration bag intended for use with Delta, JET, Grizzly, Shop Fox, Harbor Freight, and POWERTEC units like the DC-1080/ DC-1081. The bag is constructed from ultra-thick material for long-term durability and keeps airflow intact while trapping up to 99% of fine dust. This option suits shops prioritizing fine-particle capture without sacrificing bag life.
Xsourcer Dust Collector Bags for Harbor Freight
Xsourcer offers a set of six bags for Harbor Freight Central Machinery collectors, with a double-layer thickness of 11 mil for enhanced durability. They’re specified as 31″ × 40″ with a 19.5″ diameter. The thicker plastic aims to reduce tears and extend service life in busy, dust-heavy environments.
Interplas Dust Collector Bags
Interplas bags are heavy-duty 6 mil plastic, designed for industrial use and broad compatibility with major dust collection systems. The 38″ × 72″ size offers substantial capacity, reducing the frequency of bag changes during high-volume dust removal tasks. Tear resistance and long-term wear are emphasized for workshop and small manufacturing settings.
Peachtree Woodworking Supply Clear Bags
Peachtree Woodworking Supply offers disposable clear plastic bags designed to replace factory cloth bags. These 5-mil thick bags reduce dust storms during bag changes and are built to resist tearing, providing reliable performance when handling dry dust and debris from woodworking operations. They fit bottom-stage dust collectors that use 20-inch filter drums.
Buying Guide
Key purchase considerations for industrial dust collector bags include compatibility, thickness, and filtration level. The right bag should fit your dust collector’s drum size and mounting method, while thicker plastic (5–6 mil) increases tear resistance and retention capacity. If your work generates a lot of fine dust, a 1-micron or finer filter bag can improve air quality and reduce airborne particles. For high-volume shops, larger dimensions and double or multi-layer constructions reduce frequent bag changes and downtime.
- Compatibility: Confirm drum diameter, length, and whether bags are designed for 35/70 gallon systems or other models.
- Material Thickness: Thicker bags (5–6 mil) resist tearing and hold up under repeated use; thinner bags may be cheaper but require earlier replacement.
- Filtration: 1-micron bags capture finer dust but may restrict airflow if too small; balance filtration with bag performance for your tools.
- Durability: Look for tear-resistant seams and reinforced areas, especially in industrial settings with heavy debris.
- Ease of Use: Disposable bags reduce dust in handling, while reusable systems should be easy to empty and reseal.
For shops that run long sessions with heavy dust loads, choosing industrial-grade bags with higher mil thickness and larger capacities can reduce downtime and maintenance. When in doubt, select a widely compatible option from established brands and verify the bag’s certifications or user guidelines to ensure optimal performance with your specific dust collection system.
