RESUN ACO 004 and ACO 006 Air Pump Diaphragm x 2 – Replacement Kit

This replacement diaphragm set is designed specifically for the RESUN ACO 004 and ACO 006 electromagnetic air pumps. Over time, diaphragms wear out due to continuous use, leading to reduced air output and increased noise. Replacing them restores the pump’s original performance and extends its service life.

Key Features:

• Includes 2 rubber diaphragms compatible with RESUN ACO 004 and ACO 006
• Precision-molded for a perfect fit and optimal air compression
• Improves efficiency and helps maintain consistent air pressure
• Durable construction for long-lasting use
• Easy to install – no special tools required

Applications:

Ideal for aquariums, seafood tanks, biofloc systems, and small aquaponics setups using RESUN ACO 004 or ACO 006 air pumps. Regular diaphragm replacement ensures uninterrupted aeration and pump reliability.
