electronicdrivernot specified

Product overview
A blower designed for higher flow applications. Model C75B1 delivers elevated static pressure and free-flow rates at a nominal 24 V while maintaining compact dimensions for OEM integration.

Key features

• Dimensions: 75 x 70.5 x 65.5 mm
• Nominal voltage reference: 24 V
• Max. pressure at zero flow (24 V): ≈13,000 Pa
• Max. flow at free flow (24 V): ≈763 l/min
• Short-term higher-voltage capability: up to ≈17,500 Pa (zero flow) or ≈860 l/min (free flow)
• Equipped with Boreasa latest-generation brushless motor; requires a driver to operate

Performance / Graphs
PQ performance is provided for 24 V operation (PQ chart available in the product documentation). Specified values correspond to nominal voltage; short-duration higher-voltage operation can increase pressure and flow as indicated.
