Description
Reliable Passive Airflow Management for Internal and External Spaces
Poor passive air circulation creates persistent challenges across both residential and commercial buildings. When moist, stale air becomes trapped within utility rooms, kitchens, washrooms, or sub-floor voids, condensation rapidly forms on cold surfaces. Over time, this stagnant environment fosters stubborn black mould, weakens structural timber, and degrades interior decor. At the same time, attempting to ventilate through exposed wall penetrations often introduces external weather problems, allowing driving rain and heavy dampness to track back inside the building envelope.
The 165 x 89mm Louvre Vent Aluminium PR6631 provides a durable, straightforward architectural solution to these ongoing airflow challenges. Designed with carefully angled hooded louvres, this compact face-fixed vent grille encourages natural, balanced air exchange while actively deflecting downward moisture, splashing, and direct spray. Its purpose-built profile allows moist air to exit freely, or fresh supply air to enter cleanly, protecting vulnerable cavities and moisture-prone interior areas from damp accumulation.
Manufactured from high-grade aluminium and finished in an understated satin sheen, the vent grille offers dependable resilience against environmental exposure. Whether installed across exterior brickwork to protect sub-floor voids or mounted internally alongside ducted air conditioning and filtration systems, it provides a tidy, professional finish that integrates smoothly into domestic, commercial, and light industrial projects alike.
Key Operational and Architectural Features
Deflection Engineering with Hooded Louvres
The downward-facing hooded louvres direct passing air smoothly while serving as an effective physical barrier against rain and external splashes. This angled design ensures your building fabric stays dry internally, preventing wind-driven precipitation from saturating inner insulation, pipe boxing, or cavity walls.
Robust Satin Aluminium Construction
Extruded from hard-wearing aluminium, the PR6631 resists corrosion, rust, and surface degradation far better than lightweight plastic alternatives. Its refined satin finish blends discreetly with modern architectural hardware, contemporary brickwork, rendered exterior elevations, and neutral internal decors.
Simple Surface Mounted Installation
With its pre-drilled flange holes, the 165 x 89mm Louvre Vent Aluminium PR6631 mounts flush against flat substrates in minutes. It fixes securely to timber lining, plasterboard linings, brick, blockwork, or duct terminals without requiring complex rebates, specialized framing, or recessing tools.
Versatile Dual Internal and External Duty
Engineered for internal or external placement, this unit performs reliably across washrooms, office suites, food preparation spaces, and exterior masonry vents. It works harmoniously alongside mechanical extract fans, filtration systems, and passive ventilation ducts.
Installation and Practical Application Stages
Stage 1 Substrate Preparation and Aperture Alignment
Clear the ventilation opening of debris, dust, and uneven masonry. Align the 165 x 89mm outer plate centrally over the opening to confirm full coverage across the duct or air path.
Stage 2 Fixing Hole Marking and Orientation
Ensure the hooded louvres slope downwards towards the exterior or floor level to promote natural moisture run-off. Mark fixing pilot holes through the pre-drilled perimeter slots using a spirit level.
Stage 3 Mechanical Screw Fastening
Pilot-drill the substrate and insert appropriate wall plugs for masonry if required. Secure the aluminium grille firmly using countersunk screws, tightening evenly to preserve a flat surface seal.
Stage 4 Final Inspection and Maintenance Review
Inspect the louvre openings to ensure an unobstructed airflow path. Maintenance remains minimal, requiring only periodic dusting or wiping with a soft, damp cloth to keep the vents clear.

Frequently Asked Questions
Can this ventilator grille be fitted externally in exposed areas?
Yes, the 165 x 89mm Louvre Vent Aluminium PR6631 is manufactured from corrosion-resistant aluminium with hooded horizontal louvres specifically angled to shed rainwater and resist splashing.
Are fixing screws supplied with the unit?
Fixings are not included. Because mounting surfaces vary widely across timber, brickwork, render, and plasterboard, appropriate countersunk screws and wall plugs should be selected to match your specific substrate.
How does this grille support air conditioning and filtration ducting?
The unit acts as an open terminal cover, permitting continuous passive airflow or serving as an intake and extract face grille that balances pressure without straining mechanical ventilation equipment.
