Filter Selection Process Overview

The website has been developed to guide the reader through the selection process of an AURORA FILTERS in exactly the same format that would be executed if one was to sit with one of our sales representatives. Each step listed below defines the exact AURORA FILTERS that best suits your needs as well as helping you to consider your potential needs in the future. That being said, this website cannot replicate every scenario and may not answer all of your questions, therefore we encourage you to gain as much insight into AURORA FILTERS here and call one of our knowledgeable sales representatives.

1 - Filter Series Selection

The first step is to determine if the A-Series of P-Series filters are needed. This can be difficult if the reader does not have experience with an AURORA FILTERS. Our sales representatives are best suited to understand what system you are using now and what your expectations are from AURORA FILTERS. The following links will take you to introductory overview descriptions of the A-Series and P-Series AURORA FILTERS.The ultimate decision comes down to the need for pressure or vacuum conditions during the filtration or drying process now or in the future. If this is the case then the P-Series AURORA FILTERS> Models should be considered.

2 - Size Determination

AURORA FILTERS are available in 14”, 20”, 26”, 36” and 48” sizes. The 14” size is available with two different capacities by restricting the jacket zone of the smaller unit to only 4” height and the 14X larger unit has a 6” jacket zone. Just recently we were asked to create a larger capacity 36” unit and thus the 36X size is now available. The datasheets for each size is listed. The size data is common for both A-Series and P-Series filters. The filter is designed to be charged from a reactor in stages as the filtrate is extracted from the filter more slurry can be added to the upper chamber. It is not necessary to size your filter to the size of your reactor. The ideal size of the filter is dependent on the approximate volume of cake that is required to be developed. The maximum and minimum cake volumes are noted for each size filter. These values are determined by the recommended minimum of 3/4" (18mm) and the maximum height within the heating/cooling jacket zone of the filter.

3 - Material Selection

AURORA FILTERS are available in four different material choices for the wetted surfaces of the filter – 316L Stainless Steel, HALAR Lining on 316LSS, ETFE 1020 Lining on 316LSS, and Hastelloy C22. Further technical information on these materials is available from AURORA FILTERS.

4 - Nozzle Flange Type

AURORA FILTERS are available in a variety of different flange type configurations. Because the AURORA FILTERS is custom built for each customer the flange type can be chosen to suit the matching configuration of hoses and other equipment in your facility.

5 - Product Chute Configuration

A variety of different product chute options have been developed based on specific customer needs. Each of the options have different features and benefits and are able to be supplied in with different outlet flange sizes to accommodate the direct connection with your isolation valve or product receiver vessel of choice

6 - Other General Options

Customization is one of the most important feature to the AURORA FILTERS. Every filter is custom made to the exact requirements of each customer. Chances are that we have supplied it so do not be afraid to ask.

7 - Spare Parts and Consumables

AURORA FILTERS lists common spare parts and consumables that have been requested by customers over the years. Each AURORA FILTERS is supplied with a price list for these spare parts which we will honour for 12 months from shipment of the new filter. By specifying the serial number of the filter in the future we are able to open the exact filter file and determine the exact size and configuration of parts on the filter that may have to be replaced, regardless if the filter has been sold or acquired by new ownership.
