Air Admittance Valves (AAVs) are one-way venting devices used in plumbing and drainage systems. They allow air to enter the drainage system when negative pressure is created, such as during water discharge from sinks, baths, or other fixtures, while preventing the escape of sewer gases and foul odours into the building. AAVs provide an efficient alternative to traditional vent stacks, helping to simplify plumbing layouts and reduce roof penetrations.
Drainage Filters / Odour Control Units are devices that incorporate carbon or mechanical filters to remove unpleasant odours from venting systems. These are particularly useful in areas where conventional venting is difficult or where air quality and hygiene are critical, such as kitchens, food processing units, hospitals, or commercial facilities.
• Small size, suitable for individual fixtures or short branch lines.
• Efficiently prevents sewer gases while allowing air intake.
• Designed for typical household or light commercial applications.
• Can be installed on branch lines or individual fixtures.
• Suitable for large drainage stacks or multiple fixtures.
• Handles higher airflow and pressure changes in commercial or high-rise buildings.
• Equipped with replaceable carbon or mechanical filter cartridges.
• Filters air in both directions, controlling odours from drainage systems or septic tanks.
• Ideal for spaces where odour control is essential.
• Valve Body: Typically made of high-strength plastics such as ABS, polypropylene, or polycarbonate for durability and chemical resistance.
•Sealing Mechanism: Silicone, EPDM, or other elastomeric membranes to ensure airtight operation.
•Filter Housing: Made of corrosion-resistant plastic or metal; contains replaceable cartridges for odour control.
•Mounting: Valves and filters are suitable for wall, floor, or pipe-mounted installations.
•Optional Features: Locking covers, insect screens, or protective caps for outdoor/semi-outdoor applications.
• Suitable for kitchens, bathrooms, and laundry fixtures in residential buildings.
• Ideal for drainage systems in commercial complexes and high-rise structures.
• Used in food processing units and industrial kitchens to manage ventilation and odour control.
•Applicable in hospitals, laboratories, and other healthcare environments requiring hygienic drainage solutions.
• Suitable for septic tanks, grease interceptors, and enclosed vent systems.
