--- title: "Coima SHK-4 & SHK-4 HS Series Dust Collectors, 5,000-6,400 CFM W/Motorized Shaker" description: "Coima Dust Collectors have become very popular in the North American market, and for good reason. They offer more sizes and options than competitors and a build quality that is hard to rival! The SHK-4 HS (15 hp) and SHK-4 PLUS (15 HP) both offer four discharge points. The SHK-4 HS is rated at 5,000 CFM and hits a static pressure of 13.5\" while the SHK-4 is rated at 6,400 CFM rates at 11\" of static pressure. The HS is going to be one step above the SHK-3 PLUS in that it will offer another discharge point. While the SHK-4 will offer a slight advantage in CFM over the HS model with a slight loss in static pressure. The COIMA SHK-4 v2 Enclosure-less Dust Collector with Shaker is built for industrial dust collection where reliable airflow, antistatic filtration, and a compact, enclosure-less installation matter. It offers a step up in airflow and filter surface area for shops with heavier dust loads or multiple collection points. Additionally, the shaker-cleaning filter system helps keep airflow consistent while reducing manual filter maintenance. With its heavy-gauge galvanized construction and NFPA-aligned design details, this unit is an excellent fit for production environments that need dependable dust capture without a full enclosure. ***Due to vendor restrictions, we are unable to advertise our lowest pricing online.

The \"SHK\" series of dust collectors have become an extremely popular choice do to the myriad of options and the over all quality of the dust collectors themselves. We have yet to see another dust collector offering such high quality hardware, fan assemblies, impellers, and over all build quality. On top of this they all come STANDARD with a top mounted shaker. Plus you have the ability to customize the SHK dust collectors to meet \"YOUR\" application needs. You can choose models from 5-20 HP featuring 1-5 waste bags. PLUS you have options like one of the highest quality dump bins we have seen that end loads but also has the ability to be side loaded with the optional wide leg adapter kit. Very few dust collectors offer side loading which is a must in many applications to save space. Other options include barrels, a hopper kit and transfer fan, and also enclosure panels. Our most popular models are the SHK-3 and SHK-3 PLUS. (note: In our testing the SHK-3  operated @ 73-78 db measured @ 5, 10, and 25' with no duct work attached) Feel free to contact us to discuss which SHK and options fit your application!
