Some of these features include the chamber design, flow rate and lid design among others.

The manufacture, installation and maintenance costs are equally affordable.

What is the Maximum Operating Pressure for PVC Bag Filter Housing?

The maximum operating pressure for PVC Bag Filter Housing is 6 bars.

However, for customized options, the maximum operating pressure for these devices may be higher/less than the above 6 bars.

What are the Features of PVC Bag Filter Housing?

Some of the features of PVC Filter Housing are:

  • A reinforced body for long service life
  • Compact design
  • High precision
  • Made using PVC material that has excellent properties suitable for low- and high-pressure applications
  • Are light weight; they are made using material that does not carry much weight.
  • Excellent corrosion resistance
  • Ultra Violet rays resistant
  • Are affordable, yet high quality
  • Support legs for support of the device
  • Some are opaque thus helping prevent any UV rays from impairing the operation of the device

What are the Components of a PVC Bag Filter Housing?

Some of these parts of a PVC Bag Filter Housing are:

i. Internal support basket; this element supports the PVC Bag Filter in its right position.

ii. Bag filter element; it is attached to the housing to facilitate the filtration of solutions/fluids

iii. Housing; it holds all of the elements inside of the device.

iv. Mounting stand; this element supports the device so it can stand on its own.

v. Sealing ring; this feature aids in the transfer of the chamber cover force all through the filter bag seal circumference.

What are the Pipe Connections for PVC Bag Filter Housing?

Some of the pipe connections for PVC Bag Filter Housing include:

  • Flange connection
  • Threaded connection
  • Socket

How does a PVC Bag Filter Housing work?

A PVC Bag Filter Housing is easy to operate.

You allow fluids to get in through the inlet nozzle of the PVC Bag Filter Housing.

It then directs the fluid flow to the bag filter put inside the device.

The bag then separates the contaminants from the fluid.

Following this, you collect a clear fluid from the outlet nozzle.

What are the Factors to Consider when Designing a PVC Bag Filter Housing?

When designing your PVC Bag Filter Housing, you have to ensure that it has the best features and capabilities.

It must operate at its maximum potential for the success of the device.

However, below are some factors to consider when designing this device:

I. Mode of Operation – Continuous/batch

The mode of operation of a device determines how the PVC Bag Filter Housing is built.

It can have a continuous or batch mode of operation.

The type of mode of operation chosen will be because of the intended applications.

II. Service Time

You should build a PVC Bag Filter Housing that can work at its optimum best over a long time.

It should have a service life of more than five years.

III. Cost

When designing your device, you must ensure that the costs are affordable.

Costs include the manufacture, installation and maintenance costs.

The cost of the raw materials must also be manageable, yet high quality.

IV. Total Suspended Solid

You have to estimate a specific volume of TSS so that the device can comfortably hold the volume.

This is regardless of the volume of fluid/substances that will pass through the filtration system.

V. Material

It should effectively function within the set maximum pressure, temperature and overall process.

It should also have properties such as chemical compatibility, durability, and corrosive resistance.

VI. Filtration Rating

The rate of filtration although is dependent on the bag filter, the resulting fluid or substance still passes through the housing outlet nozzle.

It is therefore important to place this factor into consideration when designing your device.

  VII. Operating Temperature

The PVC Bag Filter housing must withstand the high temperatures applied at a specific application.

VIII. Operating Pressure

The device should be able to effectively function at the chemical/physical process.

It should withstand the operating pressures of around or more than 7 bars.

IX. Flow Rate

You have to consider the size of the device.

This depends upon the length and diameter of the PVC Bag Filter Housing.

Whether you have a small or large PVC Bag Filter Housing depends on the calculated flow rate.

Other factors you have to consider are the specific temperature and gravity, viscosity, volume, size of particles and the desired efficiency.

What are the Quality Codes and Standards for PVC Bag Filter Housing?

Before introducing PVC Bag Filter Housings into the market, manufacturers/suppliers must ensure that they are of high quality and safe to use.
