⚙️ OVP Series Models and Technical Data
The OVP series is composed of models with various flow rates (CFM) and pumping stages (S for Single, D for Dual), often using a high-speed AC motor.
The OVP Series focuses on portability and quick pull-down, achieved via a high-speed motor. The models are segmented by capacity (CFM) and stage count (S/D).
