Nailor's 35S-CVP Series is perfect for use as a pressurization unit for critical environment applications. Utilizing Nailor's EPICTM fan technology, the fan and blower operate as a pressure independent constant volume assembly. This means that the airflow through the unit will not change due to pressure changes in the system as the filter loads or as the pressure in the exhaust or supply ducts change.

The induction port is closed so that the unit operates as a straight through cooling unit. Both electric and hot water reheat options are available. HEPA filters may be installed either upstream or downstream of the terminal unit depending on whether the room pressure is negative or positive. The fan and damper are set to maintain pressure in the room being served. Temperature control is through reheat in the unit. The CVP feature allows designers to take advantage of Nailor's EPICTM fan technology and its associated low operating costs for pressurization. "Smart" Brushless DC motor technology provides continuous monitoring, automatic compensation and precise control and maintenance of discharge airflow regardless of discharge static pressure variations incurred by a HEPA filter. Available in three units sizes, suitable for 200 – 3000 cfm (94 – 1416 l/s) zone designs with up to a maximum total external discharge static pressure of 1.0" w.g. (249 Pa). Ideally, suited to clean room applications such as hospital isolation wards, operating rooms, pharmaceutical and biotechnology manufacturing and research facilities.
