Designed for commercial transformer use, it absorbs moisture from incoming air, preventing internal damage. Its color-changing gel provides a clear visual cue for replacement, ensuring optimal performance and longevity. With a precise 1.27 cm pipe thread and the ability to reduce dew point below -40°C, this breather is engineered for reliability and peace of mind in demanding environments. ## Description Efficacy silica gel breather is a very good absorber of moisture. It is very efficient, it may dry down air to a dew point of below -40oc. A well maintained silica gel breather will generally operate with a dew point of -35oc as long as a large enough quantity of gel has been used. Silica gel crystal has tremendous capacity of absorbing moisture. When air passes through these crystals in the breather; the moisture of the air is absorbed by them. The purpose of these silica gel breathers is to absorb the moisture in the air sucked in by the transformer during the breathing process. ... Silica gel in the breather will be blue when installed and they turn to pink color when they absorb moisture which indicates the crystals should be replaced. ## Features - Contains: 1 Piece | Quantity: 500 Grams | Polycarbonate With Aluminum Top - Weight: 500 Grams | Pipe Thread: 1.27 Cm (0.5 Inch) - The Purpose Of These Silica Gel Breathers Is To Absorb The Moisture In The Air Sucked In By The Transformer During The Breathing Process - Silica Gel Breathers Are Filled With Blue Silica Gel (Indicating Type) Which Has The Moisture Absorption Capacity And Signals The Saturation Degree By Changing Its Color - Silica Gel In The Breather Will Be Blue When Installed And They Turn To Pink Color When They Absorb Moisture Which Indicates The Crystals Should Be Replaced ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | EFFICACY | | Floor Area | 1 32nds | | Colour | Blue | | Special Feature | Automatic Moisture Removal | | Capacity | 1 Centiliters | | Tank Volume | 1 Centilitres | | Product Dimensions | 10D x 10W x 10H Centimeters | | Recommended Uses For Product | Commercial | | Item Weight | 0.5 Kilograms | | Material | Aluminium | | Model Name | Aluminium top | | Manufacturer | WALTZER INDIA, WALTZER INDIA, Balaji Market, Hawa Bangla, Indore Madhya Pradesh .Ph.
