Product Overview
Construction details
501
• Stainless steel components.
The components used for the elimination of air like float, sliding
guide zones, spring and mechanism stem are made of stainless
steel. In this way they minimize the friction and ensure maximum
reliability.
• Protection device
The venting air is passed through a forced passage and a filter
with a thin mesh strainer. This arrangement avoids the danger
of leakage due to debris, that can be deposited between the seat
and the mechanism.
• High venting capacity
The size of this deaerator makes it suitable for applications on
large pipes, particularly on horizontal sections (distribution
manifolds in central boilers applications) or wherever it is
required to release large quantities of air from the system.
• Threaded outlet Installation
At the top of the device there is
a 3/8” Female threaded exhaust
connection which is suitable for
connecting a conveying pipe.
