Ceiling Mounted Aluminum Fume Extraction Arm with Gas Spring Balance

RY-XQ-AL01 Ceiling Mounted Aluminum Fume Extraction Arm

A ceiling-suspended extraction arm that carries its own weight on a pneumatic gas spring rather than on friction knobs. Two telescoping tubes slide against each other, the swivel base turns a full 360 degrees, and the hood end adds a short corrugated flex section so the last few centimetres can be aimed by hand. The whole arm is anodised aluminium with a transparent polycarbonate bell hood.

Key Features

• Gas-spring balance — a pneumatic cylinder carries the arm weight, so the hood can be moved multi-axis with one hand and stays locked at any angle without the joints being over-tightened.

• Dual telescoping tubes — a 700 mm 125 mm-bore section and a 580 mm 100 mm-bore section slide inside one another, giving variable reach instead of a fixed-length arm.

• 360 degree swivel base — the base under the ceiling column turns a full circle, so the arm can be swung between two benches without remounting it.

• 1000 mm square ceiling column — an aluminium square column with a 170 x 200 mm bolted flange sized for a load-bearing soffit.

• Transparent PC bell hood — a 375 mm polycarbonate hood rated to 120 degrees C, transparent enough to watch the reaction underneath while fumes are drawn away.

• Damper knob at the hood — the airflow control valve sits at the hood end rather than at the ceiling, so the operator sets it while standing at the bench.

• Quick-fit duct collar — a 100 mm or 110 mm connection collar takes flexible duct directly, which keeps the installation to one joint at the ceiling.

• Anodised aluminium body — the finish resists acid and alkali vapour, organic solvents and thermal ageing, with nylon and stainless joint assemblies instead of plated hardware.

Typical Applications

University chemistry benches, atomic absorption spectrometry, GC and HPLC instruments, organic synthesis sinks, pathology grossing tables and precision soldering stations, where the hood has to be moved between instruments many times a shift and re-positioned with one hand.
