CLEAN AIR WITH DF SERIES AIR FILTERS

Why Filter Air?

So why filter compressed air? Compressed air delivered directly from an air compressor is usually not suitable for its intended use due to several factors:

  • Atmospheric air in an industrial environment is most likely contaminated with pollutants such as particulate matter, moisture and hydrocarbons.
  • The air inlet filter on an air compressor is a particulate filter, designed to protect the air compressor and not any downstream equipment requiring further filtration.
  • The discharge temperature from the air compressor may be too high for distribution & use.
  • Oil-carryover from the air compressor and air receiver scaling.
  • The presence of condensation leaving the after-cooler as the compressed air is cooled.

DV Systems’ DF Series Air Filters effectively reduce contamination in your air stream while maintaining a low pressure drop, ensuring your compressed air system delivers clean compressed air to your facility.

If the proper filtration isn't implemented, contamination, such as dirt, water & oil will deposit on the inner surfaces of pipes and fittings causing an increase in pressure drop (a loss of energy used to compress air).

In addition to satisfying an applications particular compressed air requirements, dry, cool, clean air most likely always results in lower operating costs.

Features & Benefits
DF Series Air Filters

  • The patented smooth bore flow insert further minimizes turbulence and pressure drop.
  • Industrial-grade brass float drain, which discharges accumulated condensate & oil reliably.
  • High effective filtration area and high dirt holding capacity.
  • Removable dual-indicator gauge displays differential pressure drop & operating efficiency (zero impact to pressure drop).
  • Easy to install and replace with a no-touch filter element & visual alignment to prevent over-tightening.
  • The proprietary internal and external corrosion-resistant coating provides enhanced corrosion protection in harsh environments.
  • Features 4 filter element cartridges for all canister sizes.
  • Optimizes air system efficiency with a very low pressure drop.
  • CRN Registered

Filter Elements
1 → 0.001 Micron

DF series air filter elements range from 1 micron coalescing filters to 0.001 micron activated carbon absorbent filters.

Series A → 1 Micron

The Series A Filter is a mechanical coalescing filter, which removes all liquid, water, oil aerosols and solid particles 1 Micron and larger, providing class 3 compressed air according to ISO-8573-1.
Note These filters are needle felt white and display a clear base without tags for identification purposes.

Series P → 0.1 Micron

The Series P Filter is a mechanical coalescing filter, which removes large liquid loads & particles 0.1 Micron in size and larger, providing class 2 compressed air according to ISO-8573-1. Polyester & stainless steel support media results in cleaner compressed air and increases durability in use.
Note Take note that these filters are necessarily preceded by the 1 Micron Series A filter. These filters are needle felt white and display a double-dashed line for identification purposes.

Series E → 0.01 Micron

The Series E Filter is a .01 mechanical coalescing filter, which removes up to 99.99% of oil aerosols, providing class 1 compressed air according to ISO-8573-1.
Note Take note that these filters are necessarily preceded by the 1 Micron Series A Filter and the .1 Micron Series P filter. These filters are needle felt white and display a single-dashed line for identification purposes.

Series V → Carbon Filter

The Series V Filter is an activated carbon absorbent filter, which removes oil vapour and odour, providing class 1 compressed air according to ISO-8573-1. Take note that these filters are necessarily preceded by the 1 Micron Series A filter, the .1 Micron Series P Filter and the 0.01 Micron Series E Filter.
Note These filters are without needle felt white and display a clear base without tags for identification purposes.

Pressure Drop
What Is It?

Let’s talk about pressure drop and how a low pressure drop is critical in maintaining an efficient and properly functioning compressed air system - Pressure drop is a reduction in air pressure from the air compressor discharge to the actual point-of-use.

Pressure drop occurs as compressed air travels through the treatment and distribution system. Flow restrictions in the system require higher operating pressures than are needed in the system. This is known as artificial demand, which significantly increases energy costs.

A properly designed air system should exhibit considerably less than a 10% percent pressure drop from the air compressor’s discharge pressure (measured from the the air receiver tank to the point of use). Excessive pressure drop results in poor system performance and excessive energy consumption. Minimizing differentials in all parts of the system is an important part of an air system’s efficient operation.

The highest pressure drops in a system are usually found at the point-of-use, leaks in piping and hoses, and FRL’s (Filters, Regulators and Lubricators).

To put things in perspective, pressure drop accounts for over three quarters of the ownership cost of a compressed air filter.

DF Series air filters address this directly by minimizing pressure-drop:

  • The DF Series air filter’s patented smooth bore flow insert directs air into the filter element, minimizing turbulence and pressure losses.
  • The DF Series air filters deep-pleated filter element design further minimizes pressure drop.
