Product Description

Aqua Sonic Electronic Fouling Control – EFC200


EFC utilises advanced Ultrasonic technology, to create an effective and environmentally friendly alternative to conventional marine fouling control.

By using EFC Ultrasonic technology, you can avoid the considerable time, effort and expense that you would normally associate with applying conventional coatings. EFC will enhance the performance to the extent that annual lift outs will not be necessary [apart from boat maintenance in general] and whereas, you would be expected to re-apply antifoul as a seasonal expense, you could be looking to do this on only a three or four year, perhaps even five year basis using EFC.

How it works

EFC uses pulses of Ultrasonic frequencies to deter micro organisms from attaching themselves to your motor boat or sail boats hull. This pulsing effectively creates an invisible shield around the boats hull protecting it from these micro organisms commonly referred to as Bio-foul.

The ultra high frequencies are not harmful to humans, fish, plant life or any other marine based life forms.
