Hygroscopic Breathers and Disposable Hygroscopic Breathers

Disposable Breathers

Remove moisture & particulate before it enters the fluid containing reservoir

Beach Disposable Hygroscopic Breathers

Beach disposable breather elements are state-of-the-art in design and function, and are the industries best choice for assuring maximum machine performance.

Beach offers these Disposable Breathers cost saving benefits:

  • Elimination of water-contaminated oil which prevents additive stripping
  • Elimination of rust-forming condensation
  • Elimination of sludge deposits
  • Less abrasive particles to prolong machine operating life
  • Longer oil and oil filter life

Resilient Construction, Multiple Application

Every Beach disposable tank breather is manufactured in a durable, shock-absorbing clear plastic casing with resilient qualities to withstand the customary abuse associated with heavy manufacturing equipment. The units are disposable. Manufactured with environmentally safe components, they can safely be disposed of as solid waste.

Beach disposable tank breathers are manufactured in five sizes: BB-B, BB-1, BB-2, BB-3, and BB-4 to accommodate different mounting space requirements. The BB-B and BB-1 are designed for small applications and rated for air flow of 3 cfm. All other models are rated for 16 cfm flow of air in and out of the tank or reservoir.

The patented air flow design filters wet, dirty air through the unit, multiple 3 micron polyester filter elements remove solid particulate and the color-indicating silica gel extracts the moisture. When the air is expelled from the container, the top foam pad prevents oil mist from contacting the silica gel or entering the atmosphere and allows a partial regeneration of the hygroscopic agent, and a backflushing (cleaning) of the particulate filter when the air leaves the reservoir.

Other Beach hygroscopic breather product lines include Rebuildable Steel breathers for large storage and process tanks, Extreme Duty breathers for rugged and corrosive industrial environments, and Hybrid breathers with bladders and check valves for low flow and wash down applications.

Unique Filtration Process

Moisture and particulate accumulation are major factors of oil contamination in industrial equipment. Neglected, these detriments restrict equipment efficiency, causing machine downtime and significant expense in replacement oil, parts and repair labor. Beach breathers incorporate a proven, field-tested design. They prevent water and contaminants from entering fluid reservoirs as differential pressures occur through thermal expansion and contraction of the fluid, or during the filling or emptying process. Manufactured with a hygroscopic agent, Beach breathers have the capability to extract water vapor from the air as it is drawn through the unit. Accompanying solid particulate is then removed by a patented polyester fabric filter, allowing only clean, dry air to enter the system.

Extreme Duty Breathers

Beach Product Line XD-6 Extreme Duty Breathers are designed for harsh environments, especially construction, mining and marine applications. With a shock and vibration resistant shell, check valves, and a large desiccant bed, the XD-6 is our toughest, longest lasting disposable breather.

Benefits include:

  • Eliminates rust forming condensation

  • Prevents sludge deposits and water contaminated oil

  • Provide longer oil and filter life

  • Reduced wear and tear on equipment, prolongs life

  • Helps reduce operating costs due to repair: parts, labor and down time

Extreme Duty Breather Features

Automotive grade nylon housing and solid standpipe design offer increased vibration resistance and temperature range

Three layers of particulate protection to .3μ

Water blocking filter media prevents free water from entering the breather

Clear windows for easy system monitoring

Color indicating silica gel changes from blue to ping when breather needs replacing

Check valve system extends product life

Hygroscopic Breathers

Beach Hygroscopic Breathers Beach Rebuildable Steel breathers are unique, patented air filter and water vapor removal systems. They replace the standard breather or ventilation system on virtually all types of industrial equipment, tanks and reservoirs.

Industry spends millions of dollars annually treating the negative effects of contamination caused by wet, dirty air. Contaminated lubrication oil and hydraulic fluid results in excess machine wear, production downtime, and repair costs. Likewise, contaminated products in storage and process tanks result in spoilage and waste. Beach hygroscopic breathers attack the cause, thereby preventing expensive problems caused by contamination.

How the Beach Rebuildable Steel Breather Works

As wet dirty air is drawn through the unit, a micro glass pleated filter removes particles down to1-micron and the hygroscopic agent extracts moisture.

When the air is expelled from the container, the pleated filter cleans itself by releasing dirt back into the atmosphere. The hygroscopic agent is partially reactivated by the dry air passing back through, thereby permitting longer periods between recharging or replacing.

Benefits of Beach Breathers

  • Elimination of water contamination in oil and related fluids.
  • Increased oil and oil filter life.
  • Reduced abrasive wear, downtime, and repair costs.
  • Elimination of rust and corrosion inside container.
  • Improved lubricant performance
  • Eliminate chemical reactions or spoilage.
  • More reliable equipment performance.

Various Sizes Adaptation to virtually any system

Carbon Steel or Stainless Housing Handles high temperatures & extreme environments, prevents corrosion

More on Rebuildable Steel Breathers

Rebuildable steel breathers were designed specifically for applications where there are very high temperatures, extremely dirty air, or corrosive environment. They are ruggedly designed, with housing of epoxy coated carbon steel or stainless steel.

The hygroscopic agent (desiccant) is enclosed in a bag of polyester filter material. This desiccant bag filter is easily installed when it is time to replace or recharge the unit. The amount of water each model is able to absorb before recharge or replace is indicated in the chart below.

The 1-micron pleated filter has a very large surface area, resulting in long service life. Like the bag filter, it is easily replaced without removing the breather from service. The Rebuildable steel breathers accommodate large air flow rates with minimal pressure drops.
