If you are still comparing models, see which dust extractor fits your grinder.
The JF84 is the dust extractor JFURTHER builds for contractors who grind concrete for long stretches and cannot afford to stop and clean filters. 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.
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.
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.
One long bag replaces fixed drums: pull, cut, seal, dispose. Faster changeovers and far less airborne dust during emptying.

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.
The standard D50 accessory kit is 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.

Not the right fit if: you only grind intermittently and do not need automatic cleaning — the JF82 (manual, 410 m³/h) costs less and is simpler; if you need more airflow, choose the JF85 (620 m³/h, automatic) or the JF83 (620 m³/h, manual).
It suits small and mid-size 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.
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.
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.
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.
Through the continuous bag: pull the bag down, cut and seal it. The dust stays enclosed, which reduces exposure during disposal.
