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). Each separator shall be Caleffi model
546 or approved equal. (See product instructions for specific installation
information.
DISCAL
®
air and dirt separator
546 Series, Steel 2 - 6 inch Flanged
CALEFFI
Application
Air and dirt separators are used to continuously remove the 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 microbubble level.
The DISCALDIRT
®
air and dirt separator also removes any solid impurities
in the system. The impurities collect at the bottom of the device and can be
flushed through the integal drain shut-off valve. The circulation of fully
de-aerated and cleaned water enables the equipment to operate under opti-
mum conditions, free from noise, corrosion, or mechanical damage.
