Submittal Data 02920 NA — Issue Date 04/2011
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.

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.
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
NA546 or approved equal. (See product instructions for specifi c installation information.)
