Keep your camper fresh and dry with this 100mm stainless steel butterfly vent, built tough for New Zealand’s coastal conditions. Designed for campervan conversion projects, it gives you smooth airflow control while keeping rain and salt spray out. A solid, reliable choice for any van build or upgrade.

Benefits:
• Prevents condensation and stale air build-up inside your van.
• Marine-grade stainless steel for long-lasting rust resistance.
• Side knob opens and closes smoothly, even with cold or wet hands.
• Perfect for campervan conversion projects needing durable ventilation.
• Reduces dampness and mould during off-grid trips.

Features:
Made from 304 marine-grade stainless steel, this vent is built to handle coastal air, damp forest tracks, and humid summer nights without rusting. The 100mm butterfly design gives you precise airflow control – crack it open overnight for gentle ventilation or open it fully to clear cooking steam fast. The side knob is easy to grab in tight van spaces, and the low-profile faceplate sits flush when closed, keeping your van’s exterior clean and streamlined. It’s a proven choice for campervan conversions where reliable, space-saving airflow matters.

People are asking

Where is the 127mm butterfly vent typically installed?

The 127mm (5 inch) stainless butterfly vent is typically installed in the side or lower panels of a campervan to ventilate fridge bays, battery compartments, under-floor spaces, or general living areas. The butterfly valve allows airflow to be controlled manually.

Is stainless steel the right material for a van vent?

Yes. Stainless steel is ideal for exterior van applications as it is corrosion resistant, UV stable, and handles coastal NZ conditions without rusting or degrading. It also gives a more premium look than plastic alternatives.

What size hole do I cut for the 127mm butterfly vent?

Cut a round hole of approximately 127mm (5 inches) diameter for the vent body. The flange sits over the hole and is screwed to the panel. Always seal around the flange with appropriate sealant to prevent water ingress, particularly on exterior installations.
