Offering up to 15% increased hydraulic performance compared to the original Laing D5 PWM, the Revo offers revolutionary vibration-reduced circulation due to the spherical motor having only one moving part. The rotor is held in place by a single ball bearing, made of extremely durable ceramic and thanks to the fully rounded design it ensures ease of installation at any angle in either horizontal or vertical orientations for flexible tube routing possibilities.
