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.

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 brass
body with large internal volume. seals in EPDM, blowdown drain port, and removable
internal glass-reinforced nylon fi ber 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 specifi c
installation information.)

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 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 a drain shut-off cock. 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.
