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

The JF84 is the automatic filter-cleaning version of the 410 class. It is a 2.4 kW, two-motor, single-phase dust extractor with automatic cyclical filter cleaning: one motor's filter is pulsed clean while the other keeps working, so suction stays steady throughout the shift.

It delivers 410 m³/h of airflow and 220 mbar of vacuum — the same capacity as the manual JF82 — but it cleans itself. 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.

Automated cleaning cycle

The JF84 uses automatic cyclical filter cleaning: it automatically pulses reverse air back through one motor's filter while the other motor keeps 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 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.

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.

Not the right fit if: you need more airflow for a large multi-head grinder — choose the JF83 (620 m³/h, manual) or the JF85 (620 m³/h, automatic); or if you only grind occasionally and the dust is low — choose the JF82 (410 m³/h, manual).

الأسئلة الشائعة

Is the JF84 suitable for my grinder?

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

How does automatic cleaning work?

The JF84 uses automatic cyclical filter cleaning: it automatically pulses reverse air back through one motor's filter while the other motor keeps 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 JF82 and the JF84?

Both deliver 410 m³/h at 2.4 kW with H13 filtration at 0.3 μm and continuous bagging. The JF82 uses manual reverse-air cleaning (you clean the filter when suction drops); the JF84 cleans automatically on a cycle, so it suits longer continuous grinding.

Can the JF84 run on a different voltage?

Standard supply is single-phase 220 V, 50 Hz (2×1.2 kW, 410 m³/h). Other voltages can be customized, including 110 V (2×0.8 kW, 360 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.

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.
