This is an Industrial Fume Extractor made by Sentry Air Systems. This is the Dual 10' Model # SS-500-D10FA-MP1 It can be used in a multitude of applications such as: Machinery industries Chemical industries Food processing Pharmaceutical labs Welding Metal-working Photoelectric industries Nail salons Welding Laser cutting or engraving Soldering Cutting Sanding Chemical applications We have used it exclusively for welding fumes. After approximately 8-years, we just replaced the motor and control panel for roughly $2K and it has a brand new set of filters for $1600.00. The unit itself is $9500.00 ($10,100.00 to California). So, roughly $12-13K new with shipping and tax if you were to buy a new one today. We are no longer in need of it and we just got it all dialed in to sell. Although this unit is not brand new, it functions like new and the price is significantly reduced! I won't charge tax and although I can ship it, I would prefer to sell it locally. Cash only and in person only please! If shipping it, I will need a wire transfer and will ship it after the funds have cleared. If the ad is up, it's still available. Please don't waste my time with low offers and please don't ask me to email you at some address, reach out to your Brother, Dad or Uncle... Just call, text or email me if you are a real person and are truly interested. Thank you for looking!
