Welcome to ourDrizgasCompany!
Drizgas Tech Engineers are specialists in all types of industrial fume extraction. We are manufacturer of fume extractor for various industrial application.
Fume extraction is becoming more necessary solution for industrial companies in the wake of continued research findings and government recommendations. Having a good grasp on what fume extraction systems are and how they work is important as you begin to consider fume extraction in your plant.
Much like a conventional household vacuum, a fume extraction system is like a vacuum you would use at home, but instead is designed specifically for fume collection and filtration.
A fume extractoris a device to capture fumes and particles using blower and takes into filtration system for cleaning the captured fumes before releasing into the atmosphere.
Industrial processes create fumes or particles such as sanding, grinding, welding, spraying, powder filling, and chemical applications.
Fume extractors use various type of filters while some systems, depending upon application, use multiple filters in line. The combination of the powerful fan and high quality filtration media creates a recirculating air pattern for ductless units. This units reduce the power consumption and duct works. Also, these units take up only less space and have easy access to change filters.
The inner housing of a fume extraction unit has a filter and a motor that creates negative static pressure. From a functional standpoint it is a simple system. The unit create vacuum pressure using a blower. These industrial-designed systems use specific blowers to get the very high static pressure.
Extraction units connect to any kind of properly fitted extraction hose kit to bring you as close as possible to the type of air pollution you are trying to capture. The fume extractor can be attached to fume generating machine, welding machine, laser cutting machine, soldering machine etc. in order to collect fumes at the source.

For activated carbon and specialty-blended filters, the efficiency depends on the chemical being adsorbed and the application. These types of filters are used to adsorb organic vapors and solvents. Activated carbon has millions of pores that create a large surface space to adsorb odor and chemical fumes. These types of filters do become saturated and must be replaced to optimize efficiency.
