Dimensions
Flow capacity
The fl uid velocity at connections for DISCALDIRT 546 series air and dirt
separators is recommended to not exceed 10.0 f/s. Above this speed,
heavy internal turbulence and noise can occur and air and dirt elimination
effi ciency begins to fall measurably. Optimal air and dirt elimination
performance occurs at fl uid velocities of 4.0 f/s or less. See the fl ow
capacity chart.
We reserve the right to change our products and their relevant technical data, contained in this publication, at any time and without prior notice. Contractors should request production drawings if prefabricating the system.

Hydraulic characteristics
Typical Specifi cation
Furnish and install on the plans and described herein, a Caleffi DISCALDIRT
air and dirt
separator as manufactured by Caleffi . Each separator must be designed with a side drain
valve and automatic air vent. The separator design must include a large internal volume,
and a stainless steel internal screen to automatically remove all dirt present in the system
with particle separating capacity to 5μm (0.2 mil). The separator must be constructed in
accordance with the latest revision of the ASME Boiler and Pressure Vessel Code and
stamped for 150 psi (10 bar) working pressure. Each separator shall be Caleffi model
546 or approved equal. (See product instructions for specifi c installation information.)
Application
Air and dirt separators are used to continuously remove air and debris contained
in the hydronic circuits of heating and cooling systems. The air discharge of
these devices is very high. They are capable of automatically removing all of the
air present in the system down to the micro-bubble level. The DISCALDIRT
®
air and dirt separator also separates any solid impurities in the system. The
impurities collect at the bottom of the device and can be removed through
the drain pipe, to which a separately sourced drain valve can be mounted.
The circulation of fully de-aerated and cleaned water enables the equipment
to operate under optimum conditions, free from noise, corrosion, localized or
mechancial damage.
