High-quality welding air filtration system manufacturers will apply their
own fume extractor to actual effects and quality, instead of a mere marketing
name, in order to gain some fluke psychology.
Nowadays, under the influence of various environmental protection issues at
home and abroad, more and more welding fume collector manufacturers have
gradually realized that this so-called fluke psychology method is no longer
useful, thinking that the essence of manufacturing enterprises lies in the
quality and technology of equipment and machinery. , Service and other factors
determine market development.
The prerequisite for the success of the dust collection system is to
effectively capture industrial dust. The capture speed and configuration are
both important parameters for the design of dust hoods. ACGIH (American
Conference of Government Hygienists) provides meaningful guidance for the
recommended capture speed of dust hoods. ACGIH proposes according to the type
and energy related to dust emissions A series of capture speeds, including
factors such as dust toxicity and heavy productivity.
For example, for wet sanding that splashes heavy particles from a
high-speed grinding wheel, a capture speed of 2000 ft/min may be required, while
a low-density dust may require 200 ft/min. The geometry and location of the dust
hood are also important. A hose picker in a 2-inch Shop-Vac is not enough to
capture the dust released during the drum filling process. Conversely, a
semi-circular slotted manifold around the perimeter of the top of the drum will
be more effective. With the discharge of high-momentum particles, the
directional dust hood captures the trajectory of the particles, thereby using
the flow energy to capture the dust entering the pipe.
Many welding dust extractors are the result of Pure-Air's advanced
technology for many years. Combining technology with reality is the source of
our development and growth.
