Electrostatic Precipitator
RB700
The RB700 is a small-capacity, industrial-grade electrostatic air cleaner with an integrated blower, designed for industrial and manufacturing environments where a self-contained filtration unit is needed without the ductwork and separate fan of a full inline system. It collects both dry and wet particulates — dust, oil mist, welding and process fume, and airborne fines — from 0.01 to 10 microns at up to 95% efficiency, removing them from the air stream before discharge. With three selectable airflow settings up to 700 CMH, it suits individual machine tools, single-cell workstations and small production areas.
Typical applications include CNC and machine shops, metalworking and grinding cells, welding bays, workshops, laboratories and light production lines. The RB700 is trusted by install contractors, consultants, plant and facilities managers across UK industry. Need more capacity in the same compact format? See the RB1000.

Understanding System Performance in Real Applications
How it's works
Air is drawn in by the unit's own double-inlet centrifugal blower and pre-filtered before passing through the electrostatic collection cell. Particulates from 0.01 to 10 microns are electrically charged at 12KVDC and drawn onto oppositely charged collection plates at 6KVDC, capturing dust, oil mist and fume at up to 95% efficiency with a low, stable pressure drop — so airflow doesn't fall away as the cell loads, the way it does with disposable media. The high-frequency solid-state power supply is self-regulating, with short-circuit and arc protection, auto-restore, an automatic cut-off when the door is opened, and an LED indicator that tells you when the cell needs washing.

- Notes
on
Application
Suitable for individual machine tools and single-cell workstations — CNC, milling, turning, grinding and EDM — where oil mist and fine particulate need capturing at source.
Self-contained: the integrated blower removes the need for a separate extract fan, making it well suited to retrofits, leased units and sites with no existing extract provision.
Widely used in welding bays, workshops, laboratories, packaging lines and light production areas requiring fine particulate removal.
Ceiling-suspended or frame-mounted, with left-to-front or right-to-front airflow for flexible siting around existing plant, racking and services.
Washable collection cells mean no recurring media spend — a lower running cost than bag or panel filtration on continuous-duty applications.
Detailed Technical Information, Compliance & Performance Data
Is the RB700 suitable for my application?
The RB700 suits single machine tools, individual workstations and small production areas where the extract requirement sits at or below 700 CMH — CNC and machine shops, welding bays, grinding and polishing cells, workshops, laboratories and light assembly lines. Suitability depends on the contaminant type, the volume of air being handled, duty cycle and discharge location. We assess these before recommending a unit. For higher volumes, the RB1000 or our ducted RY range will be the better fit.
