Linear Diaphragm Compressors
Instructions for
Operation • Safety • Warranty
These linear diaphragm compressors are very durable and the continuous
duty motors are designed for years of service. Ideal for aerating ponds,
water features, bait tanks and large aquariums.
• 115 volt motors are super quiet
• Weatherproof enclosures - can sit outdoors without damage
• Energy efficient - operates on only a few watts of power
• Reliable - linear compressors have few moving parts making them very reliable

Installation Instructions:
1. The first step of installation is to attach one end of the tubing to the compressor. Some tubing will attach
directly to the compressor, other sizes may need to use the short piece of rubber hose that is included
with the compressor. If tubing is connected directly, simply slide tubing onto outlet of compressor and
clamp. If an adapter hose is needed, slide one end onto compressor and clamp - the other end can be
connected to the tubing using an adapter so the two sizes will hook to each other.
2. Before attaching the other end of the tubing to the air diffuser, trim the tubing to your desired length
Once trimmed you can attach the tubing to your diffuser and secure with a clamp. You may have to add
weights to the tubing to get it to sink. If you purchased self weighted tubing then you will not need to
add weights.
3. Install the diffuser in the location of choice in your pond. Note: In freezing climates it is recommended
that you do not locate the diffuser in the deepest part of the pond — this is the warmest water in
freezing conditions and should not be disturbed.
4. Put the air compressor in a location so that it cannot fall into the water. While the compressors are
weather resistant, it is still advised that you shelter your compressor from the elements. Direct rain and
snow may shorten the life span of the unit. Note: In the winter damp air can condense on the inside wall
of the hose. This can eventually block the hose completely, it is important to check the hose frequently
during freezing temperatures.
