(i) a second housing having an inlet and an outlet, the inlet connected to receive air into the second filter assembly from an outlet of air moving equipment, and the outlet of the second filter assembly configured to deliver clean air from the second filter assembly; and (ii) a second filter element within the second housing, the second filter element comprising a particulate filter portion constructed and arranged to remove particulate contaminants.
- 12. The air filtration assembly according to claim 11, wherein the chemical filter portion of the first filter assembly comprises at least one adsorbent material.
- 13. The air filtration assembly according to claim 12, wherein the chemical filter portion comprises a first adsorbent material and a second adsorbent material.
- 14. The air filtration assembly according to claim 11, wherein the particulate filter of the first filter element comprises a cellulose material.
- 15. The air filtration assembly according to claim 11, wherein the particulate filter of the first filter element comprises a polymeric material.
- 16. The air filtration assembly according to claim 11, wherein the particulate filter of the second filter element comprises depth media.
- 17. The air filtration assembly according to claim 16, wherein the depth media comprises fiberglass.
- 18. The air filtration assembly according to claim 17, wherein the depth media comprises a first fiberglass media and a second fiberglass media.
- 19. A power producing assembly comprising:
(a) a first filter assembly comprising:
(i) a first housing having an inlet and an outlet, the inlet configured to receive dirty air into the first filter assembly, and the outlet configured to deliver clean air from the first filter assembly; (ii) a first filter element within the housing, the filter element comprising a particulate filter portion constructed and arranged to remove particulate contaminants from the dirty air; and (iii) a chemical filter portion arranged to remove chemical contaminants from the dirty air; (b) an air compressor having an inlet and an outlet and operable to move air from its inlet to its outlet, the inlet of the compressor being connected to receive air from the outlet of the first filter assembly; and (c) a second filter assembly comprising:
(i) a second housing having an inlet and an outlet, the inlet connected to receive air into the second filter assembly from the outlet of the compressor, and the outlet of the second filter assembly configured to deliver clean air from the second filter assembly; and (ii) a second filter element within the second housing, the second filter element comprising a particulate filter portion constructed and arranged to remove particulate contaminants from the air from the compressor.
