Enviro-Safe Air Enhancer Direct Inject for Systems Up to 15 Ton #2000AI-15 Description Air Enhancer for systems up to 15 ton Part #: 2000AI-15 Enviro-Safe Air Enhancer is an air conditioning performance booster specially formulated treatment designed to enhance cooling properties of new and old air conditioning and refrigeration systems by reducing mechanical friction up to 1500%. Air Enhancer contains a highly polar molecule that works synergistically with compressor oil to improve the performance of air conditioning and refrigeration systems by increasing heat transfer in the condenser and evaporator coils. The polarized molecule bonds to the metal inside the system by removing the insulated build-up of oil and forming a conductive layer to improve heat transfer. One-time use Concentrated No need to pump-down R410 or other units No injection-hose or caulk-gun needed Concentrated formula means less material in the system DO NOT use in ammonia systems For Use In: Heat pumps Split systems mini split units Packaged units Microchannel coils Payment Shipping Returns Payment is required at the time of purchase through payments.
