1. Introduction

1.1 Cartridge ﬁlters

Cartridge ﬁlters are widely used in industrial and domestic applications for removal of suspended solids in water. The variety of cartridges available and the confusing methods of ratings, however, make selection of cartridges diﬃcult for consumers. It becomes important for users, therefore, to understand cartridge ﬁlters, how they work, and how manufacturers rate them.

1.2 Filtration

Filtration is a process of removing unwanted solids from ﬂuids by passing the ﬂuid through a form of sieving material that retains the solids, but allows the ﬂuid to pass through. Filtration eﬃciency is, therefore, the percentage of solid retention by the sieve. It is this “sieve” that we refer to as the ﬁlter medium, or simply the ﬁlter. A contaminant is generally referred to as the material that is to be removed from the ﬂuid, and the clean ﬂuid is called the ﬁltrate. In today’s market, manufacturers use three types of ratings to evaluate ﬁlters: nominal rating, absolute rating and beta ratio.

1.3 Nominal ﬁlter rating

A nominal ﬁlter rating is an arbitrary value determined by the ﬁlter manufacturer, based upon removal of some percentage of all particles of a given size or larger.

- The rating is typical based on a weight percent (etc. 60 -95%)

- The 5-40% that pass through are NOT deﬁned by the manufacturer (normally much larger particles pass through).

- The rating is based on a weight analysis test.

- There is a high risk of channelling when a ﬁlter medium has some oversized pores or a wide pore-sized distribution.

- There is a high risk of bypass when cartridge-to-housing seal is ineﬀective.

1.4 Absolute ﬁlter rating

The absolute rating or cut-oﬀ point of a ﬁlter refers to the diameter of the largest hard spherical particle, normally expressed in micrometres (µm), which will pass through the ﬁlter under speciﬁed test conditions.

- The ﬁlter is tested under a speciﬁc international well known test method (modiﬁed OSU-F2 single-pass ﬁlter test system).

- The rating is based on a particle measuring test.

- The ﬁlter is reproducible.

- Higher ∆P does not result in particle unloading.

- The ﬁlter can withstand ﬂow pulsations as well as viscosity and temperature changes.

- There is no risk of channelling due to the high quality of the ﬁlter media.

- Absolute ﬁltration means that the ﬂuid is ﬁltered both horizontally and vertically. In comparison, an inferior nominal type of ﬁlter will allow particles which are more than 10 µ in length to pass the ﬁlter, as it only ﬁlters the ﬂuid according to the diameter of the particles.

- It is NOT possible to reproduce the ﬁlter.

- Particle unloading is rising when the ∆P across the ﬁlter increases

2. Requirements

2.1 Filtration requirement

To achive warrenty and assure the service intervals stated from Danfoss, the PAH, PAHT, APP pumps require water with no particles larger than 10 micron (10 µ). Thus a 10 µ absolute ﬁlter with a Beta value > 5000 must be used.

- 10 µ means that particles of 10 µ or larger in size will be caught by the ﬁlter.

β-value of ﬁlter Filter eﬃciency

2 50.00% 50,000

4 75.00% 25,000

10 90.00% 10,000

20 95.00% 5,000

40 97. 50 % 2,500

100 99.00% 1,000

200 99.50% 500

The Beta value > 5000 refers to the eﬃciency of the ﬁlter. A ﬁlter with a Beta value of > 5000 catches 99.98% of the particles being 10 µ or larger. This means if there are 100,000 particles in the ﬂuid (10 µ or larger), only 20 of them would pass through that ﬁlter. Other types of ﬁlters on the market have a Beta value > 10 (90% eﬃciency), and these ﬁlters would allow 10,000 of the 100,000 particles to pass through the ﬁlter.

Number of particles downstream for each

100,000 particles upstream

500 99.80% 200

1,000 99.90% 100

2,000 99.95% 50

5,000 99.98% 20

10,000 99.99% 10

2.2 Filter types

Pleated polypropylene ﬁlter elements use the very latest gradient density micro-ﬁbre media technology to provide a combination of excellent absolute micron ratings, high ﬂow rates, and high dirt-holding capacity.

2.3 Features

- The absolute particle retention provides excellent protection of the pump and the rest of the system.

- Compatibility with a broad range of process chemicals allows use in most applications.

- High ﬂow rate and long service life ensure minimum downtime of the system.

- High dirt-holding capacity.

- Filter element is easily exchanged.

2.4 Applications

The Danfoss ﬁlters can be used in a wide range of demanding applications such as:

- General water ﬁltration

- RO/DI water ﬁltration

- We recommend CIP cycles in the range of 3-10 PH

2.5 Right ﬁlter choice

There are 2 factors to consider in order to choose the right ﬁlter: a) The ﬂow through the ﬁlter b) Amount of dirt in the ﬂuid (E.g. SDI).

If the ﬂuid is relatively clean (low SDI), the ﬁlter choice can be based on the pump size as this will indicate the ﬂow through the ﬁlter.

If the ﬂuid is relatively dirty with small particles, a larger ﬁlter size should be chosen to increase the dirt-holding capacity. For instance, for a ﬂow of 60 l/min ﬂuid containing many small particles a ﬁlter for a ﬂow up to 170 l/min should be chosen.

If the ﬂuid is relatively dirty with larger particles, a cheaper and less eﬃcient pre-ﬁlter should be placed in front of the main ﬁlter. This will ensure a long life of the more expensive main ﬁlter, as most of the larger dirt particles will be caught in the cheaper pre-ﬁlter. The preﬁlter may be of the type ”Nominal ﬁlter”.
