70nm: We design and manufacture complete windscreen wipers systems

Performance Window Wipers for the Marine, Rail and Commercial Industry

70Nm HEAVY DUTY COMPACT WIPER MOTOR

With the ever increasing need for speed and the 24 hour day operation of today's shipping the 70Nm model gives outstanding performance. To ensure a good swept window albeit travelling at 60 knots, the wiper arm design needed to ensure a good blade contact has necessitated the development of the extra heavy duty model.

Supplied as fixed and variable arc models and available from 48 volts to 220v DC and AC, the standard motor has two speeds and self parking facility which can be operated by a rotary switch, toggle switch or a multi speed/function control switch. Insulated earth return is standard.

Pantograph and pendulum arms up to 60 inches (1525mm) are available and blades up to 39 inches (1000mm).
