• Engine Compartment Ventilation - Exhaust vent for engine room ventilation systems
• Fuel Tank Ventilation - Outlet for fuel tank vent lines
• General Ventilation - Exhaust point for cabin and compartment ventilation
• Galley Ventilation - Exhaust for cooking area ventilation systems

Installation Guidelines:

When installing the blower and exhaust grille, it is recommended to place the louvered ventilator in a reasonably protected area (for example, in the cockpit rather than on the transom) to prevent water intrusion into the ventilation circuit. An extra precaution consists of building an elbow in the hose to create a water trap that prevents seawater from entering the ventilation system during rough conditions.

Installation Instructions:

1. Select Location - Choose protected area for grille installation (cockpit preferred over transom)
2. Cut Opening - Cut 102mm diameter hole in mounting surface
3. Insert Hose - Connect ventilation hose to grille using notches and lugs
4. Secure Hose - Use stainless steel hose clamps to secure hose to grille
5. Mount Grille - Position grille over opening and secure with 4 screws from outside
6. Create Water Trap - Build elbow in hose to prevent water intrusion (recommended)

Hose Connection:

The grille features integrated notches and lugs that hold the ventilation hose in the correct position. However, the hose must also be secured with stainless steel hose clamps for a watertight, secure connection. This dual retention system ensures the hose won't pull loose during vessel operation or rough seas.

Compatible Systems:

• Bilge Blowers - Works with standard marine bilge ventilation blowers
• Inline Fans - Compatible with inline ventilation fans
• Passive Ventilation - Can be used for passive ventilation systems
• 4" Hose - Designed for standard 4-inch (102mm) ventilation hose

Care & Maintenance:

• Inspect Regularly - Check grille for cracks or UV damage
• Clean Louvers - Remove debris and salt buildup from louvers periodically
• Check Hose Connection - Verify hose remains securely attached
• Tighten Screws - Check mounting screws are tight and secure
• Replace if Damaged - Replace grille if cracked or damaged

Essential component for marine ventilation systems. The fuel-resistant polypropylene construction ensures long-lasting performance in harsh marine environments. The louvered design allows efficient airflow while the protected mounting location prevents water intrusion. Easy 4-screw installation makes replacement or new installations straightforward.
