Typical Specification
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 brass body with large internal volume, seals in EPDM,
blowdown drain port, and removable glass-reinforced nylon fiber mesh
(PA66GF30) internal element screen/coalscing medium to automatically
remove all air present in the system and all dirt present in the system, with
particle separating capacity to 5μm (0.2 mil). Each air and dirt separator
shall be a Caleffi model 546 or approved equal. (See product instructions
for specific installation information.)
DISCAL
®
air and dirt separator
546 Series, Brass
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
optimum conditions, free from noise, corrosion, or mechanical damage.
