If you are still comparing models, see which dust extractor fits your grinder.

The JF82 is the dust extractor JFURTHER builds for contractors who run a small or mid-size floor grinder on standard single-phase power. Two independently switched motors deliver 410 m³/h of airflow, so you can run one motor for light clean-up or both for active grinding. It is the manual-cleaning model in the range: when suction drops, close the inlet with the lift handle and use the reverse-air blowback to knock dust off the cartridges — no hose removal, no clouds of dust around the machine.

A continuous bagging system handles disposal. Concrete and silica dust falls into one long transparent bag; you pull it down, cut it at any length and seal it, so the operator never tips an open drum of fine dust. An hour meter, forklift-friendly base and a height-compressible frame (approx. 1,155 mm packed height) keep fleet management and export shipping simple.

Two motors, controlled independently

Each motor has its own switch. Match suction to the job, reduce noise and power draw on light work, and keep working on one motor if the other is being serviced.

H13 filtration for fine concrete dust

Two-stage membrane-coated cartridges filter dust down to 0.3 μm at H13 level, protecting operators during dry concrete grinding where respirable dust is the main hazard.

Manual reverse-air cleaning, done safely

Close the inlet by lifting the open/close handle, then blow back. Unlike older designs, you do not pull the hose off and block the inlet by hand, which is where secondary dust exposure usually happens.

Continuous bagging disposal

One long bag replaces fixed drums: pull, cut, seal, dispose. Faster changeovers and far less airborne dust during emptying.

Built to ship and to move

The frame compresses in height to cut freight volume, and the base can be lifted directly by forklift. Fitted castors handle day-to-day movement on site.

Applications

Dry concrete grinding and floor preparation with small to mid-size grinders
Epoxy removal, surface preparation and general floor clean-up
Workshops and rental fleets that need single-phase, plug-and-work extraction

Not the right fit if: you grind continuously for full shifts and cannot stop to clean filters — choose the JF84 automatic cleaning version (410 m³/h) instead; or your grinder is a large multi-head machine — need more airflow? JF83 with 620 m³/h or the JF85.

Frequently Asked Questions

Is the JF82 suitable for my grinder?

It suits most small and mid-size single-phase floor grinders. Send us your grinder model and disc size in the inquiry form and we will confirm the match before you order.

How do I clean the JF82 filter?

Manually: lift the handle to close the inlet and operate the reverse-air blowback. It takes under a minute and you do not need to remove the hose.

What is the difference between the JF82 and JF84?

Same airflow class (410 m³/h), different cleaning: the JF82 is cleaned manually, the JF84 cleans its filters automatically in cycles, which suits longer continuous grinding.

Can the JF82 run on a different voltage?

Standard supply is single-phase 220 V, 50 Hz. Other voltages can be customized — state your voltage and plug standard in your inquiry.

How is dust emptied?

Through the continuous bag: pull the bag down, cut and seal it. The dust stays enclosed, which reduces exposure during disposal.

What accessories are included?

Standard D50 accessory kit included: D50 x 7.5 m wear-resistant hose, aluminium S-wand, crevice tool and floor brush. An optional front suction bar (approx. 70 cm) speeds up final floor cleaning after grinding.
