Too often, focus is given to the purchase price of the equipment versus determining ongoing associated expenses. Read more on page 8 Dust Collection & Air Pollution Control Process dust and powders are controlled by the high-volume air cleaning offered by large-capacity dust collectors from Micro Air Clean Air Systems and its exclusive Roto-Pulse cartridge cleaning system.

Dense Flow pocket elbow is designed for use on pneumatic conveying pipelines, and is most effective when highly abrasive materials are being transported.

The ProFlapPlusIII is a passive isolation valve that self-closes by the pressure wave created by an explosion inside a vented dust collector and prevents flame propagation to upstream processes. The ProFlapPlusIII is ATEX certified for organic and inorganic dusts with KST values up to 300 bar.m/s for duct sizes ranging from 5 to 12 in. in diameter, and KST values up to 200 bar.m/s for duct sizes ranging from 14 to 40 in. in diameter.

In this version, the new hose is ideally suited for applications from the transport of powdery solids, through to gaseous media and steam extraction. It is also particu- larly suitable for blowers and compressors. The plastic hose can be used in operating temperatures of up to 110°C (short-term up to 125°C). It features small bend- ing radii and is kink-proof. The suction and blast hose is generally tape boxed and compressed which saves delivery costs and ensures minimum storage space.
