Dust Collector Woodworking Machine Spare Parts Vacuum Durable Dust Collector Bags

A two-bag set for CNC router vacuum dust collectors: an upper bag in polyester mercerized cloth for air flow and a bottom bag in polyester woven fabric for dust load. Sizes include 470mm and 510mm diameters in 1000mm and 1500mm lengths, plus 485mm and 630mm options. Bags come in steel ring or strap style. Confirm your collector's ring or strap diameter and bag length before ordering, then send those dimensions with your enquiry.

When a dust collector stops pulling chips from the CNC router, the bags are often the first place to look. A clogged upper bag cuts airflow; a worn bottom bag drops dust back into the shop. Replacing the pair restores the separation the machine was built around and keeps the working area clear.

This is a two-bag set: white polyester fiber upper and bottom bags for CNC router vacuum dust collectors and extractors. The upper bag uses polyester mercerized cloth with twill texture; the bottom uses polyester woven fabric with a cross grain pattern. Sizes include 470mm, 485mm, 510mm and 630mm diameters, in 1000mm and 1500mm lengths.

Upper bags mount by steel ring or strap and focus on air permeability; bottom bags take the dust load and focus on durability. Check the ring or strap groove on your collector before ordering, and measure the bag length you remove. A correct ring or strap fit keeps the bag seated while the machine runs.

Bags ship as upper and bottom versions; customisation is supported for dimensions beyond those shown. For a quote, send the ring or strap style, the diameter and length you need, and the collector model. If your size is not on the list, include your measurements so the bags can be matched to your machine.

What the specification fixes, and what it leaves to the machine:

• Upper bag airflow — Polyester mercerized cloth with twill texture lets air pass through the upper bag, which supports vacuum pull at the CNC router.
• Bottom bag wear — Polyester woven fabric with a cross grain pattern gives the bottom bag a durable layer where dust collects and drops.
• Diameter fit — Bags come in 470mm, 485mm, 510mm and 630mm diameters, so you can match the ring or strap size on your collector.
• Length choice — You can order 1000mm or 1500mm bag lengths to match the clearance above and below the collector housing.
• Steel ring mounting — Steel ring style seats the bag on a rigid ring, which holds the bag open and keeps the fit steady during collection.
• Strap mounting — Strap style secures the bag with a strap, which suits collectors where the bag is tied or clamped to the housing.
• Upper and bottom sets — Each set includes an upper bag and a bottom bag, so you replace both stages together and keep the dust path consistent.
• White bag visibility — White polyester fiber shows dust buildup and wear on the bag surface, which helps you decide when to clean or replace.

What changes on the shop floor when the right part goes back in:

• Keep vacuum pull at the tool. An upper bag in polyester mercerized cloth is made for air permeability, which helps the dust extractor maintain suction at the CNC router.
• Handle the dust load below. The bottom bag uses polyester woven fabric for durability, so the bag that collects and holds wood dust is built for repeated fills.
• Replace both stages at once. Upper and bottom bags are supplied as versions of the same set, so you can renew the full dust path instead of mixing old and new bags.
• Match the collector you run. With 470mm, 485mm, 510mm and 630mm diameters and 1000mm or 1500mm lengths, you can pick the bag size that fits your housing.
• Choose ring or strap fit. Steel ring and strap styles let you match the mounting method already on your dust collector, so the bags seat the way the housing expects.
• See buildup before it costs you. White polyester fiber makes dust buildup visible on the bag, which helps you plan cleaning or replacement before airflow drops.
• Ask for the size you need. Customisation is supported, so when your collector falls outside the listed sizes, you can send measurements and request a matching bag set.

Match the ring or strap diameter and bag length to your collector. Sizes include 470mm, 485mm, 510mm and 630mm diameters in 1000mm and 1500mm lengths; send your measurements if none match.

The upper bag is polyester mercerized cloth with twill texture for air permeability; the bottom bag is polyester woven fabric with a cross grain pattern for durability. They serve different stages of dust collection.

Yes, the product covers upper and bottom bag versions. Confirm the style and size for each position when you enquire so the set matches your collector.

Choose the style your collector housing already uses. Steel ring style seats on a rigid ring; strap style secures with a strap, so check the mounting point before ordering.

Customisation is supported. Send the diameter, length and ring or strap style you need, and the bags can be made to match your collector.

Both bags are polyester fiber. The upper bag uses polyester mercerized cloth with twill texture, and the bottom bag uses polyester woven fabric with a cross grain pattern.

Check for visible dust buildup, wear or loss of suction at the CNC router. White polyester fiber makes buildup easier to see, so inspect the bags during regular cleaning.

Send the bag position, ring or strap style, diameter and length, plus the collector model. If your size is not listed, include your own measurements for a custom match.
