The company has expanded its product offering for its Model SP ceiling exhaust fans and Model CSP direct-drive inline cabinet fans, for applications where low sound levels are required. A size 6.5 has been added to the Model SP family, offering air performance up to 100 cfm and a sone rating of less than 2.0. The SP-6.5 utilizes the same fan housing as the current models with a lower cfm, says the company. The Model CSP fan now offers three additional sizes, including the CSP-7, CSP-9, and CSP-12, which offer economic alternatives for performance up to 185 cfm and static pressures up to 0.75 in. wg.
