Monobloc Mixer Tap with Aerator Nozzle

The 900115 is a robust monobloc mixer tap featuring a movable swan neck and an aerator nozzle. Constructed from solid brass, both the body and the swan neck ensure exceptional durability. The tap is finished with a Rilsan powder coating, making it highly resistant to wear and tear—a feature that has made it a popular choice in schools and laboratories alike.

The innovative aerator nozzle infuses air into the water stream, creating a softer flow and significantly reducing splashback. This design is particularly advantageous for rinsing various items, ensuring a cleaner and tidier workspace. The inlets are fitted with 2 x 3/8″ BSP connections, and the tap is supplied with braided tails for a flexible installation.

This monobloc mixer tap is also WRAS approved, confirming its compliance with UK regulations.

Several variations of the model are available. Please contact us for pricing and availability:

• 900116 – Monobloc mixer tap with removable nozzle
• 900119 – Monobloc mixer tap with a fixed swan neck and removable nozzle. The swan neck is brazed into position.
