Custom Fans
Northern Blower’s substantial reputation was built on its ability to design and adapt products specifically for the needs of customers with very particular requirements. From relatively common API 560 and API 673 specification conformance, to out-of-the-ordinary dual-fan unitary base design complete with fiberglass deck structure, Northern Blower has demonstrated the engineering ability to create unique fan solutions.
