Description

C65S1 releases a new type of c65s1 series fan, especially for the domestic sleep ventilator Market. With low cost and low noise as the design goal, the fan is one of the lowest noise fans in the current industry. C65s1 fan is divided into four performance levels, with a maximum pressure of 6600 PA and can maintain 250 LPM @ 4500 PA. Overall dimensions: 65 x 63 X 48 mm. This model is available in 12 VDC and 24 VDC Miniature blowers: 1. Small (diameter 54-105mm) but high performance, max pressure up to 14kpa. 2. High pressure, high speed(max up to 60000rpm). 3. High efficiency, power conversion efficiency up to 55%. 4. With internal drivers. 5. Made of biocompatible, medical grade materials 6. Long life, over 30,000 hours in bi-level mode. 7. Low noise, <29 db in home ventilators. To maximize the reliability, all of Boreasa blowers are using brushless DC motors and are supplied with high quality dual ball bearings. An internal temperature sensor is available on most blowers for sensitive applications to ensure that the motor will not overheat. Most of the blowers described in this brochure are made of biocompatible, medical grade materials. How about customized service? Although Boreasa has a standard line of products, we also work with customers to supply them with customized products meeting their needs. Our appreciation of the customers' system performance requirements, thermal constraints, mechanical interface, noise, and cost factors allows Boreasa to offer unique solutions for our customer's applications.
