LK 770 AeroSafe is used to continuously remove gases / air from

hydraulic circuits.

With an integrated stainless-steel mesh and large area of the

chamber, the air / gas can be efficiently collected and automat-

ically released. The venting outlet is located on the side of the

top, which minimizes the risk of ice formation and blockage

when installed in places where freezing temperatures can occur.

However, the product should always be insulated if there is a

risk of freezing temperatures.

If cleaning is required, the inner part can be easily dismantled

using the quick-release connection.

If LK 770 AeroSafe is installed in connection with, for example,

an air/water heat pump that uses flammable refrigerant gases

(such as R290), it is important that LK 770 is installed outdoors

or in well-ventilated areas where there is no risk for ignition (in

case of leakage between the heat exchanger and the circuit with

refrigerant gases).

In addition to the top cover and float mechanism, the LK 770

is made of stainless steel to maintain a high quality and avoid

hazardous substances such as lead.
