Industrial ventilation systems, dust, and fume extraction systems are found in an amazing array of applications in industries large, small and in between. Fabricators, manufacturers, miners, scientists, artists, and entertainers all have uses for exhaust fans for fume and particle removal systems. There are a wide variety of these systems to fit all these applications and many more. The removal of dust, smoke and fumes is critical to the well being of workers in almost every industry.
Lumber and wood products mills, steel mills and foundries, textile mills, ceramics and aerospace material mills and factories are some of the industries where particle and fume removal is needed on a large scale. Huge turbines and impellers are needed to move the gigantic volumes of air needed to handle the giant amounts of waste dust, smoke, or fumes generated at these scales.
Crude oil refineries, petrochemical refineries and factory scale chemical manufacturers of all kinds must deal with highly volatile, flammable, and toxic organic fuels, lubricants, and solvents. The air inside them has to be protected as much as is practicable. Fans are needed to run sophisticated air entrainment systems like laminar flow hoods and positive room pressure to protect the workers inside the plant.
In the mining and quarrying industries, the lives and health of the workers depend in part on the management of dust. Coal dust, in particular, can be explosively combustible if ignited in the proper suspension ratio with air – just a spark will do. Dust extraction keeps this dust below danger levels. Powerful blowers and turbines ventilate and cool underground mines, and run even more vents and dust extractors during transport, storage, and ore processing.
Small or large fabricators depend on these heavy-duty fans to remove dust and fumes from the work area. Ambient air fume collection systems, ductless fume hoods, robotic welding hoods, dust extraction systems, and airborne particle filtration units are some of the air and particulate waste management systems available. These increase in sophistication when capturing and containing more toxic, physically hazardous, and volatile materials.
Pharmaceutical, biological, chemical, and physical research and industries deal with diverse biological, chemical, and physical hazards. Blowers drive laminar flow hoods, fume containment systems, dust collection units, air filters, chemical scrubbers, and negative pressure containment rooms contribute to worker and environmental safety. These applications often demand the highest standards as many of the substances or agents handled can be deadly in very small quantities, or pathogenic and contagious.
Many of the same endeavors listed in the preceding paragraph not only have the need to protect the environment from their products and by-products, they have to protect their products from the environment as well. Ultra clean facilities meet amazing part per million standards. High output blowers to maintain positive air pressures after driving huge volumes of air past dust extractors, HEPA filters and electrostatic precipitators to maintain the input air and.
Industrial ventilation fans will likely remain the “simple machines” at the heart of air-quality devices. They will continue to keep the environment and millions of workers safer. The staggering pace of research and industrial development will find ever more uses for this critical technology.
