ANODES
COWL VENTILATORS

Protection by means of anodes is a ”must” for all metal parts under
3 different types of cowl ventilators: water. Therefore anodes are required for wooden, fibre glass and
1. Cowl ventilators made of silicone aluminium hull’s. The material of zinc anodes is of the highest
2. Cowl ventilators made of Polyvinylchloride possible standard, the U.S. mil.-A-18001 K. specifications. Anodes
3. Stainless steel cowl ventilators which do not meet these specifications have little or no effect.
To prevent water from entering the ventilator you can install a ANODES
dorade box. Aluminium anodes consist of an aluminium-indium-zinc alloy Mil -

COWL VENTILATORS A - 24779 (SH). All anodes are streamlined and mounted either with
studs which can be welded to a steel hull, or with through-hull bolts
for fibreglass and wooden boats. We supply these studs and bolts
separately.
ELECTRIC VENTILATORS

This barely audible electric ventilators are specified for saloons,
cabins, galleys and toilets and is also ideal for heat extraction near
a refrigerator. It can be installed in both ceilings and bulkheads. It
can be used in combination with deck ventilators UFO and
UFOTRANS.

PZ (AI) PORTHOLE

We have a wide range of portholes in categories AI to AII.
• AI is suitable for installation in the hull
• AII is suitable for installation on deck
• AIII is suitable for installation in the coachroof
BATTERY CHARGER
PZ (AI) PORTHOLE
Our battery chargers have a four stage IUoU charge programme
and are extensively tested, including a 2G vibration test, to meet
our quality standards and ensure long term operation.

These chargers are compatible with Lead Acid, Li-ion, Gel and AGM
