What is desiccant Breather?
What is a Desiccant Breather? The desiccant breather replaces the standard dust cap or OEM breather cap on equipment, offering better filtration to protect against even the smallest particulates that destroy the effectiveness of your machinery, and cause downtime and costly repairs.
How do you measure a desiccant breather?
Desiccant breathers are sized according to the required cubic feet per minute (CFM). Always choose a breather with a higher CFM capacity than the CFM requirements of your tank or reservoir.
When should we change desiccant breather?
A common question that comes up when discussing how desiccant breathers work is how long do they last? Most breathers last anywhere from three to six months if properly sized.
What does a hydraulic Breather cap do?
Hydraulic breather filters remove solid particulates from incoming air to ensure the hydraulic system continues to perform as intended for the duration of its expected service life. As indicated above, air breathers play a critical role in hydraulic systems.
What is silica gel breather?
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.
How do you select a breather?
Breather size is always determined by the maximum fluid movement in/out of the fluid reservoir. Not all equipment, for example gearboxes, may specify a CFM value. If needed you can use this rule of thumb o calculate the CFM and select the correct breather for the application: 7.5 GPM = 1 CFM.
What is a breather cap?
The Breather Cap from Buyers Products acts as a ventilator to provide a free flow of clean air into your reservoir. It features oil-resistant filter elements that keep out dirt and dust particles as small as 40 microns. Breather cap sizing ranges from 1/8 in.
What is the purpose of the vent in a hydraulic fluid reservoir?
The hydraulic system needs a vent because the oil level in the tank must be free to go up or down as oil comes back from and goes out to the hydraulic cylinders when you operate the tow truck bed. When someone defeats the vent, they usually do so without intending so.
What is breather why and where is it used?
A breather is an accessory of liquid-immersed power transformers attached to the conservator tank. They serve as the breathing point of the transformer. The breather contains silica gel crystals which have a tremendous capacity of absorbing moisture.
Is standard for silica gel breather?
Specification of Silica Gel –Orange colour Indicating Type General: This specification governs the quality requirements of Indicating type Silica Gel Orange impregnated with an organic indicator with having high absorption capacity. It will be used in transformers breathers.
What is a desiccant filter?
A desiccant is a special adsorbent material with a high affinity for water. This special material has hygroscopic properties that allow it to maintain a dry immediate environment by pulling and holding water molecules within itself.
What is breather vent?
Breather vents have many applications, including vacuum relief or pressure equalization on gear boxes, oil tanks or reservoirs. Common uses can be found on single acting cylinders or valves to prevent dirt and foreign particles from entering ports open to the atmosphere.
Why is hydraulic oil out of breather?
The oil level is too low. Low enough that the intake port or pick-up tube in a reservoir is able to draw in air. This can cause aeration of the oil and as that bubbly or foamy oil rushes back to the tank, it can be more than the tank volume and can come out of the vent cap.
Does a hydraulic system need a vent?
What breather means?
Definition of breather 1 : one that breathes. 2 : a break in activity for rest or relief. 3 : a small vent in an otherwise airtight enclosure.
Why silica gel is used in breather?
Silica gel is used in breather transformers for controlling the level of moisture and prevents it from entering the equipment. They are mainly useful in protecting the transformer oil from the damaging effects of moisture. Silica gel blue crystals and orange beads work effectively in this application.
What is a breather assembly?
Description: Cat breather assemblies are designed to allow ventilation of the engine crankcase and prevent air filter contamination through trapping removal of oil vapors and other contaminants. Attributes: Breather assembly includes crankcase breather, tube and 90° elbow.
What is a breather used for?
The Breather® is a respiratory trainer/exerciser that improves lung strength and capacity by improving oxygen uptake to vital organs. It trains both inspiratory and expiratory muscles independently with the dial control features.
Should a hydraulic tank be vented?
How does a desiccant breather work?
As air is drawn into equipment through the breather, the layered desiccant filter elements remove particulate while the desiccant beads strip harmful moisture. While in service or during shut-down, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.
What is inside a transformer desiccant breather?
All Transformer Desiccant Breathers (except Re-Actrans) are filled with self-indicating silica gel. This desiccant is blue when active and turns pink when saturated.This allows a visible assessment of the condition of the desiccant. Various sizes and types of packs of this desiccant are available for recharging the desiccant containers.
What is a desiccant breather dryer Bde?
The distinctive feature of the desiccant breather dryers BDE is that it has two separate chambers. These chambers are possibly fillable with two desiccants, which in combination increase total water retention (two-stage dewatering).
How do I know if my desiccant breather is hydrated?
As the breather’s silica gel becomes absorbed with moisture, it turns a different color. Color varies depending on the brand of desiccant breather but for example, the silica gel may start out blue and turn purple when fully absorbed with water. This is how you’ll know it’s hydrated and time to replace the filter.
