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

The JF85 is the dust extractor JFURTHER builds for contractors who run a large multi-head floor grinder continuously and cannot afford to stop and clean filters. It is a 3.6 kW, three-motor, single-phase dust extractor with automatic cyclical filter cleaning: one motor’s filter is pulsed clean while the other two keep working, so suction stays steady throughout the shift. It delivers 620 m³/h of airflow and 220 mbar of vacuum.

A continuous bagging system handles disposal, and an optional front suction bar (approx. 70 cm) speeds up final floor cleaning after grinding. 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. 1,147 mm packed height) keep fleet management and export shipping simple.

Three motors, independently switched

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

Automatic cyclical filter cleaning

The JF85 uses automatic cyclical filter cleaning: it automatically pulses reverse air back through one motor’s filter while the other two motors keep working, so suction is maintained. Each motor’s filter is cleaned in rotation, triggered automatically. You do not open the filter housing and you do not stop the grinder to clean filters.

H13 filtration

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.

Continuous bagging

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

Front suction bar for faster floor cleaning

An optional front suction bar (approx. 70 cm) mounts on the JF85 and sweeps dust directly into the extractor as you push it across the floor, so you finish the floor clean-up faster after grinding. The standard D50 kit handles edges, corners and stair work.

Not the right fit if: you only grind intermittently or with low dust volumes — the JF82 (410 m³/h, manual) or the JF84 (410 m³/h, automatic) costs less and is simpler.

Frequently Asked Questions

Is the JF85 suitable for my grinder?

It suits large multi-head concrete floor grinders used for continuous grinding. Send us your grinder model and disc size in the inquiry form and we will confirm the match before you order.

How does automatic filter cleaning work?

The JF85 uses automatic cyclical filter cleaning: it automatically pulses reverse air back through one motor’s filter while the other two motors keep working. Dust falls into the collection bag below. You do not open the filter housing and you do not stop the grinder to clean filters.

What is the difference between the JF83 and the JF85?

Both are high-airflow models with H13 filtration at 0.3 μm and continuous bagging. The JF83 uses manual reverse-air cleaning (3.6 kW, 620 m³/h); the JF85 cleans automatically on a cycle at 3.6 kW and 620 m³/h. Choose the JF85 for large grinders and continuous work.

Can the JF85 run on a different voltage?

Standard supply is single-phase 220 V, 50 Hz (3×1.2 kW, 620 m³/h). Other voltages can be customized, including 110 V (3×0.8 kW, 540 m³/h) — 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.
