Vibration Absorbers

SIXTEEN MODELS AVAILABLE TO FIT COPPER TUBING FROM 1/4 THROUGH 4-1/8 INCHES O.D.
EACH UNIT PRESSURE AND VACUUM TESTED, CLEANED, DEHYDRATED AND SEALED IN PLASTIC FILM
U.L. AND C.S.A. APPROVED

Packless Model VAF Vibration Absorbers are designed for installation in the suction and discharge lines of air conditioning and refrigeration systems to dampen the transmission of compressor-induced vibration through system piping.

Packless VAF's are constructed of deep pitch corrugated tubing for increased flexibility and vibration absorption, covered by high tensile wire braid for superior strength. Tubing and braid are reinforced by ferrules at each end, and connected to female copper tube ends by high temperature braze alloys. The units are designed for making sweat connections to refrigerant piping. Sixteen models are available to fit copper tubing sizes from 1/4 inch through 4-1/8 inches O.D.

Each VAF is pressure tested then carefully vacuum tested using a highly sensitive helium mass spectrometer leak detection device. Units are cleaned, dehydrated and sealed in plastic film after final inspection to maintain cleanliness and dryness prior to installation. VAF's are available either in bulk or individually boxed.

Packless VAF's are recognized under the component programs of Underwriter's Laboratories, Inc., (U.L.) and the Canadian Standards Association (C.S.A.) for application on both suction and discharge lines in sizes through 3-1/8 inches O.D., and for suction side only in sizes 3-5/8 and 4-1/8 inches O.D.

SPECIFICATIONS

* U.L. and C.S.A. approved for low side (suction side) use only.

NOTES:

All Dimensions in inches.
Due to a continuous program of product improvement, specifications and dimensions are subject to change without notice.
Packless Vibration Absorbers are also available with male copper tube ends, model numbers VAM. They are 3/4 inch longer than VAF units for sizes 1 through 4, 1 inch longer for sizes 5 through 11; and the same length in sizes 82 and up.
For unusual installations, Packless Vibration Absorbers can be provided in special lengths or with PVC coating to protect them from condensation and freezing. Please consult factory with requirements.

INSTALLATION

Packless VAF's function best when installed as close to the compressor as possible, and perpendicular to the major vibration direction as shown below.

For optimum absorption of vibration, the refrigerant line should be anchored at the end of the VAF furthest from the vibration source.

Install Packless VAF's horizontally wherever possible. Care should be taken to allow sufficient space for the VAF so that it will not be subject to static compression or tension after soldering in place. Units should be installed in a straight line; they are not intended to compensate for offset piping.

Although high temperature alloys are used to braze the joints of Packless VAF's, the torch flame should nevertheless be directed away from the ferrule when making the sweat connection of the VAF to the piping.

Packless Vibration Absorbers are compatible with the following refrigerants:

R12, R22, R23, R125, R134A, R401A, R401B, R402A, R402B, R404A, R407A, R407B, R407C, R408A, R409A, R410A, R410B, R412A, R502, R507, R508, R509
