Model TD-93 industrial control damper
airfoil blade
Application
TD-93 and TD-94 industrial control dampers are specifically engineered and qualified for use in transit tunnel systems where tight shutoff at high velocity and/or pressure is required. The TD-93 and TD-94 meet the demanding requirements for strength, leakage, and operability of NFPA-130, NFPA-502, and UL-555S.
