I received several quotations for chemical filters. The dimensions and air volume are similar, but the prices are quite different. At this time, if you don't look at the type of filter material, it is difficult to judge where the price difference comes from.
Filter material is the core functional part of chemical filters. Different filter materials target different target gases, have different capacities, have different replacement cycles, and have different costs. The quotation only says 'chemical filter' or 'activated carbon filter' without specific filter material types and applicable objects. This quotation cannot be compared with other solutions, and there is no basis for subsequent acceptance.
The expression of filter material type should be able to correspond to the specific processing object.
Ordinary activated carbon, impregnated activated carbon, and special chemical adsorbents have different functions. Ordinary activated carbon can adsorb some organic matter, impregnated activated carbon has enhanced processing capabilities for specific gases, and special adsorbents may target acid gas, ammonia or other components. For specific differences, please refer to Discussion on whether to choose activated carbon or other adsorption media for chemical filters .
It is not enough to write 'chemical filter material' in general terms. If the quotation only says 'chemical filter material' without specifying whether it is for acidic gases, alkaline gases or organic vapors, the purchaser cannot confirm whether it can handle the components of concern in the project. For specific principles, please refer to Discussion on why chemical filters should be selected according to the target gas .
The type of filter material should correspond to the target gas. For whatever gases the project will handle, the corresponding filter material type and applicable objects should be indicated on the quotation. In this way, the purchaser can judge whether the plan is suitable. For specific reporting requirements, please refer to Discussion of why chemical filter performance reports list specific target gases .
After the filter material type is determined, the quotation should also include relevant specifications and performance information.
Media configuration. The filling amount, number of layers, and structural form of the filter material will affect the processing capacity and resistance. The media configuration should be stated in the quotation to facilitate comparison of capacity and replacement cycles of different solutions. Please refer to the specific structure Discussion of the common product forms of chemical filters .
Rated air volume and applicable environment. The air volume, temperature and humidity conditions under which the filter material works will affect the actual performance. The quotation should indicate the corresponding rated air volume and applicable environmental range. For specific environmental impacts, please refer to Discussion of how long chemical filters last .
Performance data. Data such as initial efficiency, capacity, penetration time, etc. can help determine whether the filter material meets project requirements. These data need to correspond to specific gases and test conditions. For specific life assessment, please refer to Discussion of the difference between initial efficiency and lifetime efficiency of chemical filters .
Initial efficiency and capacity should be looked at separately. High initial efficiency does not mean long life. Capacity data can help determine the replacement cycle. Both are references for quote comparison.
Different types of filter media have different scope of supply and maintenance costs.
The overall replacement or the replaceable filter element. Some chemical filters have an overall disposable structure, and the entire set is replaced when replacing; some have a replaceable filter element structure, and only the internal media is replaced. The quotation should indicate which method it is. Please refer to the specific structure Discussion of the common product forms of chemical filters .
Spare parts range. Does the quote include spare filter media? How to calculate the price and cycle of subsequent replenishment? Long-term projects should focus on this one. Please refer to the specific inquiry parameters. Discussion of what parameters need to be provided for a chemical filter inquiry .
Maintenance costs. The filter material replacement cycle, downtime losses, and labor costs are all part of the long-term operating costs. The maintenance rhythm of different filter media types may be different, so these should be considered when comparing quotes. For specific management methods, please refer to Discussion on why the chemical filter replacement cycle cannot be calculated as half a year .
Compare under the same scope and protection objectives. If one quotation includes a unit-by-unit inspection report and the other only provides a batch report, and the two quotations correspond to different delivery scopes, the price difference cannot simply be attributed to the filter material. For specific scope verification, please refer to on which configurations determine the price of chemical filters . Discussion
A certain project received two quotations for chemical filters with the same dimensions and air volume, but the price difference was about 30%.
The first quotation is for ordinary activated carbon, and the second quotation is for impregnated activated carbon for acid gas. The project needs to deal with acidic gases. Ordinary activated carbon has limited ability to process acidic gases. The filter material quoted in the second quote only meets the project needs.
If you don't look at the type of filter material, you may choose the first one with a lower price, but in actual use, the outlet concentration may not meet the standard. After clarifying the type of filter media, the purchaser can judge which quotation truly meets the target.
This case illustrates: The quotation indicates the type of filter material, which is the basis for judging whether the solution matches. involving When selecting a chemical filter product series , it is recommended to provide the target gas and filter material requirements to the supplier for verification.
