Mountain Tree Circular Air Diffuser
The Mountain Tree Circular Air Diffuser is a high-performance aeration device designed to efficiently increase dissolved oxygen levels in ponds, aquaculture systems and large aquariums. Featuring a durable circular design with numerous micro-pores across the rubber diffuser ring, it produces a dense stream of fine bubbles that maximise oxygen transfer and improve overall water quality.
The diffuser is built with a heavy 304 stainless steel base, allowing it to remain securely positioned at the bottom of the pond without floating, even when connected to high-output air pumps. This stable design ensures consistent and even oxygen distribution throughout the water column.
The diffuser ring is manufactured from high-quality eco-friendly rubber, featuring irregular microscopic pores that release extremely fine air bubbles. This increases the contact area between air and water, resulting in more efficient oxygen dissolution and improved conditions for fish and beneficial bacteria.
With a smooth, rounded profile, the Circular Air Diffuser is safe for fish and prevents injuries in ponds and aquatic environments. Combined with a durable PA plastic air nozzle and corrosion-resistant materials, it offers long-term reliability for demanding aquatic applications.
Designed for versatility and performance, the Mountain Tree Circular Air Diffuser is ideal for koi ponds, fish farms, aquaculture facilities and large aquatic filtration systems where consistent oxygenation is essential.
