What this manufacturer offers
浙江安耐特风机制造有限公司 identifies its location in Tangpu, Shangyu, Shaoxing. Its official catalogue groups fans by civil/commercial buildings, warehouses, underground spaces, industrial ventilation and fire/duct components. The reviewed DBF entry is unusually useful because its original images contain model coding, twelve air-port arrangements and separate A/E performance tables.
DBF ordinary ventilation and the modified DSF smoke-extraction version are different purchasing decisions. The source’s high-temperature statement belongs to DSF; it cannot be applied to a normal DBF quotation. The displayed certificates and test report also name different subjects, so each must be matched to the proposed fan rather than treated as company-wide approval.
The official service commitment states defined time periods and exclusions. Those are supplier promises, not measured response history or an overseas service contract. The review below connects the available construction and selection evidence to the documents a buyer still needs.

03 / PROJECT REVIEW
Assess Annaite around the fan configuration and installed duty
Use the catalogue groups to identify a duty, then choose a specific fan
The navigation separates cabinet centrifugal fans, axial/mixed-flow/diagonal-flow fans, roof and wall units, tunnel fans, high-pressure centrifugal equipment and fire/duct accessories. A building-ventilation brief is therefore not a general request for any product under the same logo.
Provide airflow, pressure definition, air condition, installation layout, electrical supply and acoustic requirements. State whether the system is ordinary ventilation, a process application or smoke extraction. Ask the supplier to identify the exact family/configuration and the evidence needed for that system, including any duty outside the ordinary ventilation table.
Ordinary building ventilation
The reviewed DBF cabinet offers detachable construction and alternative port layouts, with A/E table entries to examine.
Select the applicable fan family and materials/protection requirements separately; a general catalogue listing supplies no universal hazardous-area approval.
The DBF construction helps plan access and acoustic requirements
The source describes a detachable metal frame and panel construction, galvanised sheet for impeller/casing, coloured outer panels, an inner microperforated galvanised acoustic sheet and fine glass-wool infill. Aluminium-alloy frame profiles are described as an option. Suspended and floor installation are discussed.
These construction details help a buyer specify maintenance openings, cabinet dismantling and access to the selected motor/drive arrangement. They do not establish a guaranteed room sound level or a fixed corrosion class. Ask for the actual panel/material specification, selected orientation, lifting/support details and access envelope on the approved drawing.
Match certificate images to their named products and dates
The inspected ARES ISO9001:2015 image states validity to 5 April 2025; the inspected Certification Europe quality, environment and occupational-health/safety images state 7 March 2025. These displayed periods are past at the review date. Current renewed status was not authenticated. Management certification is also separate from a fan’s performance or fire duty.
The energy-efficiency report cover dated 21 July 2022 identifies SWF-13, not DBF, and supplies no reviewed result pages. The inspected BDWEX-900 explosion-protection image identifies a wall axial fan and states validity to 6 July 2025. Samples inspected in the fire-certificate gallery are attachments for fire dampers under certificate Z2019081814010780; an attachment says it must be used with its certificate. None is adopted as proof of DBF or DSF approval.
Management-system images
Historical displayed validity periods have elapsed; obtain readable current documents and issuer/scope verification.
An original patent publication is a defined technical record
The original CN211550023U utility-model publication names 浙江安耐特风机制造有限公司, gives a 13 January 2020 filing date and a 22 September 2020 publication date, and describes a diagonal-flow fan with motor support, guide vanes and associated features.
That publication documents a technical subject and named holder at publication. It is not a DBF cabinet specification, an authenticated current-rights report, a high-temperature test or proof of all patent counts advertised by the supplier. No patent-wide performance claim is transferred into the selected cabinet offer.
Read the after-sales promise by starting point, fault cause and geography
The supplier states a twelve-month guarantee from factory dispatch, with free repair for manufacturing-quality faults in that period. Its introduction promises telephone contact and a proposed handling opinion within four hours after a complaint. This is an initial response, not four-hour repair completion.
For urgent quality issues needing site work after contact, it states attendance within twenty-four hours in Jiangsu/Zhejiang/Shanghai and seventy-two hours outside that region. The page does not define an overseas service network or destination-specific travel arrangement. Non-manufacturing faults may incur travel/technical fees; damage outside the guarantee or caused by other factors is paid repair. Obtain written applicability, local support responsibility and parts/transport terms for the destination.
Record warranty commencement
Confirm dispatch-based dates and handling of transit, storage and commissioning periods.
Identify the actual service party, site attendance coverage, costs and exclusions for the delivery country.
Project gallery names are leads for verification, not operating results
The reviewed project index mostly uses the generic caption “case display”, with named listings for Jiujiang Zhonghui Century City and Wujiang First People’s Hospital. The index does not supply a model schedule, commissioning duty or verified present performance for those projects. No installation success rate or customer endorsement is inferred.
Ask for a comparable reference with permission to verify it, specifying fan family, selected duty, site layout and the acceptance record. For the new order, approve the fan curve/pressure basis, dimensions, port orientation, acoustic evidence and applicable conformity documents before releasing manufacture.
