Pure White PP Laboratory Fume Extraction Arm with Dome Hood

RY-XQ01W Pure White PP Laboratory Fume Extraction Arm

A three-joint extraction arm moulded entirely from high-density modified polypropylene, finished in pure white for laboratories where the extraction arm sits in the middle of the room rather than against a wall. The joints hover rather than flop, the dome hood is 375 mm across, and the butterfly damper is built into the straight duct section with a knurled knob. A ceiling flange is the standard mounting, with a wall bracket as the alternative.

Key Features

• All-PP construction — duct, joints and hood are moulded from high-density modified polypropylene, so there is no painted steel or plated hardware to corrode in acid and alkali vapour.

• Pure white UV-resistant finish — an anti-ageing surface that keeps its colour under daylight and under laboratory lighting instead of yellowing as ordinary white plastics do.

• 375 mm dome hood — a wide-mouth hemispherical dome that collects vapour rising off the bench, not only what passes straight up the duct.

• Three-joint hovering action — 360 degree swivel with pitch hovering, held by POM friction rings and tightening knobs, so the arm stays where it is placed instead of sinking under its own weight.

• Built-in butterfly damper — a stepless manual damper knob inside the straight duct section balances airflow and static pressure, so several arms can share one fan.

• Smooth 75 mm bore — the internal wall is smooth rather than ribbed, which keeps air turbulence, noise and pressure drop down over the 3 m length.

• Ceiling flange as standard — a heavy-duty mounting flange for ceiling or wall fixing, with an optional wall bracket for benches that back onto a wall.

• Shipped as a flat kit — the arm travels as moulded sections, joints and hood in one carton, with the joints assembled on site.

Typical Applications

University chemistry laboratories, pathology and histology benches, atomic absorption spectrometry, PCB soldering and electronics workstations, pharmaceutical R&D and dispensing rooms, and chemical pilot benches, where a local capture point has to be positioned over the source and then parked out of the way.
