How to uniformly configure and compare different FFU quotations? Avoid inconsistency between the complete machine and accessories

The difference in quotation does not necessarily mean the price is high or low

In FFU procurement, the project party usually receives quotes from multiple suppliers. The numbers on the quotations appear to be directly comparable, but the actual differences may come from different configuration ranges and supply contents.

A supplier's quotation may only include the complete FFU machine, excluding filters, controllers and cables. Another may include the complete machine and filter, but not the controller. Another may include the complete machine, filters, controllers, cables and test reports. The total prices of these quotes are different, but the corresponding scope of supply is also different.

It’s easy to draw the wrong conclusion if you only compare total prices. A more reasonable approach is to unify the configuration range and then compare. Aili Industrial has complete production capabilities in FFU complete machine manufacturing and can provide complete configurations and supply lists according to project requirements. For the basic structure of the FFU machine, you can refer toAili Industrial FFU fan filter unit。

How to unify the scope of supply

To unify the scope of supply, we must first clarify what is included in each quotation. It is recommended to list the following items and confirm them one by one: FFU complete machine; high-efficiency filter; primary effect or pre-filter; controller; group control system; cables and connectors; installation bracket or frame; seals; test report; use and maintenance data; spare parts and wearing parts; transportation and packaging.

For each item, confirm whether it is included in the quotation, what the quantity is, and what the specifications are. If something is not included, it needs to be made clear who will provide it and who will bear the cost.

After unifying the scope, compare the quotations of each company on the same basis. Only then will the differences truly reflect the differences in price and configuration.

How to unify the entire machine configuration

The overall machine configuration includes box material, size, fan model, motor type, control method, power supply voltage and maintenance method. FFUs with the same external dimensions may have different internal configurations. The costs of spray-coated boxes and stainless steel boxes are different. AC fans and DC fans have different costs. The structural costs of the top-replacement type and the bottom-removal type are different.

When comparing quotations, you should confirm whether the complete machine configurations of each company are consistent. If the configurations are different, the differences should be listed separately rather than directly comparing total prices. For projects that require stainless steel boxes, you can refer toStainless steel FFU understands the different configurations. For projects that require disassembly and maintenance, you can refer toDetachable FFU。

How to unify filter configurations

Filters are an important part of FFU configuration. Filter efficiency rating, size, media type, sealing method, and brand all affect price. H13, H14, U15, and U16 filters have different costs. The costs of PTFE filter media and glass fiber filter media are different. Sump seals and gasket seals have different costs.

When comparing quotes, you should confirm whether the filter is included in the quote, whether the efficiency rating and size are consistent, and whether the sealing method is the same. If one company's quotation contains the U15 filter and another only contains the H13, the total price difference cannot directly reflect the price level.

If the project requires filters to match the entire machine, you can refer toFFU is equipped with ULPA ultra-high efficiency filter to understand the interface requirements.

How to unify control and communication configurations

Controller and communication configurations also affect quotes. The costs of stand-alone controllers, group control touch screen controllers and computer group control systems are different. The communication protocols and interface forms are different, and the supporting equipment is also different.

When comparing quotations, you should confirm whether the controller is included, whether the control method is consistent, whether the communication protocol matches, and whether the group control system includes software and debugging. If one company's quotation includes a group control system and another only includes a single controller, the total price difference will be large.

For projects that require group control, you can refer toFFU/EFU group control touch screen controller andFFU computer group control system understands different control schemes.

How to unify services and fees

In addition to the equipment itself, quotes may also include different services and fees. Shipping costs, packaging costs, installation instructions, commissioning support, training, warranty periods and spare parts availability may vary. Some suppliers quote including shipping, some do not. Some include debugging, some don't.

When comparing quotes, confirm the scope of services and attribution of fees. If the scope of services is different, it should be listed separately in the quote comparison and not mixed into the total price of the equipment.

Issues that should be confirmed in advance during project communication

During the FFU quotation comparison stage, it is recommended to confirm the following with the supplier: scope of supply list; complete machine configuration; filter configuration; controller and communication configuration; cables and accessories; test reports and information; packaging and transportation; installation and commissioning services; warranty period and spare parts supply; quotation validity period and payment terms.

in conclusion

The difference in quotations of different FFU may come from the different configuration range and supply content. Before comparing quotations, you should unify the complete machine, filter, controller, cables, testing data and service charges, and then compare the prices. The same external dimensions do not mean the same configuration, and you cannot just look at the total price.
