Armstrong Filtration

Serving the greater D.C., Northern Virginia, Baltimore, and Delaware areas

Armstrong Filtration is a certified partner of the DC PACE program. The DC Property Assessed Clean Energy (DC PACE) commercial finance program provides 100% upfront financing for building upgrades. PACE allows property owners to repay the cost of energy projects over time through a special assessment on their building. DC PACE can cover hard and soft project costs, and because energy savings exceed the cost of debt, these projects also immediately improve cash-flows. DC PACE is the city's only dedicated financing tool for investing in clean energy and deep energy efficiency projects. It is privately administered by the firm Urban Ingenuity, under contract with DOEE.

As a Rosedale Products Master Distributor we carry many products including bag filters, basket strainers, centrifugal separators, and automatic backwashing filter systems. Additionally, as a systems integrator we can provide complete skid packages including Ultra Violet (UV) sterilization, pumps, and instrumentation.
