Laboratory fume extractor arm and Fume exhaust system

fume extractor arm hood is

mainly used to rapidly discharge small-scale dust, hot gas, volatile gas,
harmful gas and other small granular aerosols or gases generated in the
experiment or production process.

The fume extractor arm is
one of the essential safety equipment in the laboratory. In biological and
chemical laboratories, it is often in direct contact with highly toxic,
corrosive, flammable and explosive chemicals, often using fragile glass and
porcelain utensils and high-temperature electric heating equipment such as gas,
water, and electricity. In this environment, we carry out intense and meticulous
work, therefore, we must attach great importance to safety work. Through the
analysis of various harmful gases in university laboratories, suggestions are
put forward to strengthen laboratory management, in order to promote scientific
management of university laboratories, protect the health of operators and
surrounding personnel, and protect the atmospheric environment around the
laboratory.

structure

1. The material selection and workmanship of each component are very elegant,
with corrosion resistance, high firmness and good flexibility. Joints and
laboratory fume hoods
will not droop, and can be positioned freely according to user requirements to
meet user needs.

2. High-density PP material joints and high-density rubber joint seals that are
not easy to age are selected, which are easy to disassemble, reassemble and
clean.

3. Unique 360° rotating device

4. The telescopic duct of the extraction hood is extruded from new PP material,
which has better corrosion resistance compared with the purchased PVC parts for
other extraction laboratory fume hoods on the market.

5. The fixed base is made of high-density PVC material, which is integrally
formed by injection moulding, non-bonded, and has strong fastness and does not
come off the bottom.

6. There are no welding points on the surface of each interface of the wall-type
stainless steel base, and all the welding points are hidden inside, making the
appearance more delicate. The material of the base of the bracket is thick,
which is more convenient to install, and the appearance after installation is
high flat, smooth, no bumps, and not easy to deform.
