{"title":"Edwards Oil Filtration Systems","description":"\u003cp\u003eOil-sealed rotary vane pumps are dependable and economical, but they have two weak points: oil mist at the exhaust and oil that degrades as it picks up contamination from the process. Edwards oil filtration products address both. Exhaust oil mist filters clean the air leaving the pump, while oil filtration systems clean the oil circulating inside it. At Provac Sales, we supply Edwards oil filtration equipment for RV and E2M pumps and service the Edwards MF series filtration systems.\u003c\/p\u003e\n\n\u003ch2\u003eEdwards Oil Filtration Products We Carry\u003c\/h2\u003e\n\u003cp\u003eOur Edwards oil filtration listings include:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eEdwards EMF-20 oil mist filter, new, with KF25 inlet and KF25 outlet, a common choice for mid-size RV and E2M pumps\u003c\/li\u003e\n    \u003cli\u003eEdwards MF series oil filtration systems, which circulate and filter pump oil to remove particulates and chemical contamination\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe EMF family includes several sizes matched to pump displacement and exhaust flange. If you need a different size than the one listed, send us the pump model and we will check availability.\u003c\/p\u003e\n\n\u003ch2\u003eExhaust Oil Mist Filters: What They Do\u003c\/h2\u003e\n\u003cp\u003eWhen an oil-sealed pump runs, especially at higher inlet pressures or during pump-down from atmosphere, it releases a fine mist of oil droplets at the exhaust. Without filtration, that mist settles on equipment, benches and floors, creates odors and can be a health and housekeeping problem.\u003c\/p\u003e\n\u003cp\u003eAn Edwards EMF filter traps the mist in a coalescing element. Droplets combine into larger drops that drain into a reservoir or back toward the pump, while clean gas passes through. Many EMF filters also include an odor-reducing element and a pressure indicator that shows when the element needs to be changed.\u003c\/p\u003e\n\n\u003ch2\u003eOil Filtration Systems: What They Do\u003c\/h2\u003e\n\u003cp\u003eAn oil filtration system, such as the Edwards MF series, works on the oil inside the pump rather than the exhaust. It circulates oil through filter elements that remove:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eParticulates from the process, such as powders, metal fines and dust\u003c\/li\u003e\n    \u003cli\u003eSome chemical contamination, depending on the element type\u003c\/li\u003e\n    \u003cli\u003eDebris that would otherwise wear vanes, rotors and bearings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCleaner oil means more consistent vacuum performance, less wear and longer intervals between oil changes.
