When purchasing clean equipment, the quotation is the most prone to disagreements. The figures for the two quotes are close, but the content of the deliverables may differ significantly. One contains the filter and controller, the other contains only the host; one contains installation and debugging, and the other only arrives.
The quotation does not necessarily have to price each part separately, but it should be able to check whether it is included to avoid subsequent additional costs or delivery disputes. The following will start from the aspects of host configuration, filtering and control, installation of accessories, testing services, and transportation costs.
The quotation should indicate the host model and basic configuration, including:
Equipment models and specifications;
Air volume and external static pressure operating points;
Power and power;
Control methods and operating modes;
Material and finish.
Just writing 'FFU one' cannot verify the configuration differences. For the verification method of working points, please refer to Why should we look at the complete performance curve when selecting FFU? , the meaning of external static pressure can be referred to What does FFU external static pressure mean?。
Filters are the part of a quote that is easily missed or downgraded. It should be written:
Filter ratings and testing standards;
Dimensions and installation methods;
sealed form;
initial resistance and final resistance;
Is it included in the host quotation?
The prices of different grades of filters vary greatly. For the difference between filter efficiency and field grade, please refer to What is the difference between cleanliness level and filtration efficiency , and the difference between components and complete machine, please refer to Is FFU's nominal air volume tested with a filter?。
The control part should also be made clear in the quotation:
Controller model and function;
Speed regulation method and operation mode;
Group control or linkage interface;
Matching cables and sensors;
Is it included in the quotation?
For partition management of multiple devices, please refer to FFU group control system , understand the differences in control configuration.
Accessories and structural parts required for installation are easily overlooked:
Suspended fittings and supporting frames;
seals and transition pieces;
ducts and connections;
Fixtures and support structures;
Special installation interface.
If these accessories are not included in the quotation, additional costs may be incurred later. To determine ceiling matching, please refer to How does the FFU appearance size match the ceiling module? , for maintenance space considerations, please refer to What later expenses will be increased due to insufficient maintenance channels?。
Quotes should indicate the scope of factory testing and accompanying documentation:
Factory test items and records;
Performance data and curves;
Installation and operating instructions;
Certificates and calibration information;
Is it included in the quotation?
Factory testing and field testing have different conditions and cannot be substituted for each other. For relevant differences, please refer to What are the differences between factory testing and on-site acceptance?。
Installation and commissioning are within the scope of services and should be stated in the quotation:
Whether on-site installation is included;
Whether it includes debugging and operation confirmation;
How to divide installation responsibilities;
How to submit debugging records;
Does it include training?
Depending on the scope of services, project implementation costs vary significantly. For consideration of acceptance preparation, please refer to What preparations need to be completed before clean room acceptance?。
Shipping and packaging costs should also be specified in the quote:
Packaging methods and shipping responsibilities;
shipping costs and insurance;
Arrive at the site for unloading and moving;
taxes and other charges.
These items are easily defaulted to 'not included', so you should use the same caliber when comparing quotes.
When comparing quotes from different suppliers, you should first harmonize:
Conservation objectives and performance parameters;
filter and control configuration;
Installation accessories and service scope;
Test and data scope;
Shipping and taxes.
It only makes sense to compare prices after the functions are equivalent. For a comprehensive comparison of low purchase price options, please refer to How to check long-term operating costs for low purchase price plans?。
A certain project received two FFU quotations with similar unit prices. After checking, it was found that one copy contained filters and group control, while the other contained only the host. After comparing according to the unified range, the actual delivery differences are obvious. Adjustment method: Unify the configuration list and compare again.
Another project quotation did not list installation and commissioning, and additional costs would be incurred later. Adjustment method: Clarify the installation, commissioning and data scope in the quotation to avoid subsequent additions.
These two situations illustrate: The quotation should clearly list the scope of host, filter, control, accessories, testing and transportation services, and use a unified caliber when comparing.

Unclear quotation caliber is a common source of disagreement during the procurement stage. Aili Industrial has collaborative capabilities in fans, motors, filters, control systems and complete machine assembly. It can clearly list the configuration range corresponding to the host, filter, control, installation accessories and test data according to project needs, helping purchasers to check the delivery content of different quotations and compare plans and costs under the same caliber.
