I am the sales manager for Staclean in Salisbury, NC and would be your primary contact @ 800 438-3850. We design, manufacture, and can contract the installation of our own Staclean baghouses. We provide replacement parts for Staclean and all other manufacturer's. We handle all types of dust from many markets and from this experience, have learned many ways to improve upon older baghouse designs currently available to you. We stock silo bin vents for tanker truck unloading. We also stock a unit designed to handle the dust load from an entire ready-mix plant. We service what we sell and provide technical assistance for all dust collectors. An inventory of valves and timers plus replacement bags are maintained for same day shipment. We can offer conversions from older dust collectors to our modern design reusing the servicable parts of your current unit. Our many years of experience will earn your business.
