Tongtian / Totim · filter fan boxes and ventilation assemblies

Suzhou Tongtian Ventilation Equipment Co., Ltd.

Review filtration stage, fan duty and service access as one assembly; membership and certificate scope need to match the exact claim.

What this manufacturer offers

苏州通田通风设备有限公司 operates the reviewed souzhoutongtian.com catalogue and the Totim-branded site totim.com.cn, whose contact/footer identifies the same company. The older contact page prints 厍西路1555号 in Wujiang; the Totim contact uses 库西路1555号 in Lili Town. Confirm the exact address spelling and manufacturing/delivery location in the offer rather than silently resolving the road-name difference.

The catalogue includes initial-, medium- and high-efficiency filter fan boxes and other ventilation products. The original TY-B reference is a photo-led initial-filter box. A separate current Totim TY page publishes a series operating range and construction options; no reviewed mapping establishes that every option or rating applies to the older TY-B.

The official qualification gallery contains actual management-system and model-specific explosion-proof documents. The AMCA membership claim requires clarification: no matching Tongtian/Totim entry was located in the AMCA China member page reviewed on 11 October 2026. That observation does not establish a definitive non-membership finding, and membership itself would not certify TY-B performance.

03 / PROJECT REVIEW

Evaluate Tongtian through a complete filter-box selection

Define what the filter box must deliver at the loaded-filter duty

For a ventilation package, supply airflow and the required external static pressure together with the filtration stage and initial/final filter resistance. State the air temperature/composition and operating schedule, plus the intended noise limit and its measurement basis. Ask for the complete assembly selection with the actual filter and motor configuration.

The Totim site separates initial, medium, high, combined-stage and activated-carbon boxes. Those categories describe different treatment/supply scopes. An initial-filter box should not be represented as a complete cleanroom or pharmaceutical-process solution solely because the supplier lists those industries.

Airflow and pressure

Approve the fan’s working point after defining filter and system resistance, with power/current and control method.

Filter and seals

Identify the actual filter grade, dimensions, media, frame/seal and initial/final resistance; specify any required leakage/integrity checks.

Access and installation

Approve inlet/outlet direction, filter-removal space, service doors, mounting loads and isolation/connection details.

The TY-B photos and current TY catalogue have different evidence scopes

The original TY-B item displays the box exterior and opened arrangements, including the visible fan, filter position, service panels and support rails. No readable duty or dimension schedule accompanies those photos.

The current TY page lists direct drive, suspended/floor installation and series ranges of600–24,000m³/h and65–980Pa. It describes a standard25mm polyurethane panel, optional50/100mm panels or perforated acoustic panels, and different material/inlet/outlet choices. These are useful current-series questions, but the exact TY-B-to-TY configuration correspondence remains unverified. Obtain one selected designation/drawing and parts schedule rather than attaching the largest range or every option to the photographed box.

Read the actual ISO and TEX documents by holder, site and product

The actual quality, environmental and occupational-health management certificate images name 苏州通田通风设备有限公司 and state a16April2024–15April2027 period. They describe mechanical ventilation-equipment production and related management activities, with qualifications subject to their applicable documents. An image with an unexpired printed date does not replace issuer/current-status verification.

The displayed explosion-proof certificate inspected is GYB23.1276 for a TEX(a)-b single-suction centrifugal-fan configuration, with a printed13February2023–12February2028 period and an attachment/safety-use limitation. It is not a TY-B filter-box certificate. Confirm the exact offered fan, marking, operating conditions and full attachment if an explosion-proof duty is required.

Enterprise management

Three actual management images with a named holder/site/scope and stated period; no measured airflow, noise or filtration approval.

Actual GYB23.1276/TEX configuration document; it must not be transferred to a generic TY-B assembly.

Check the AMCA claim without confusing membership, testing and certified ratings

The supplier sites claim AMCA membership and say their fans follow AMCA standards. The AMCA China member page inspected did not show a matching Tongtian/Totim entry. Request the current registered member name and an authoritative record if that status is material; the public-page observation alone is not a final determination.

AMCA’s own Certified Ratings Program article explains that product certification concerns approved product ratings and is separate from testing to a standard; members and nonmembers can participate. Ask for the applicable certified product designation/catalogue scope where claimed. This review did not authenticate a TY-B certified-rating listing.

Supplier wording

Membership and AMCA-standard claims appear in the official introduction/TY catalogue.

Treat scale, customer and around-the-clock service claims as supplier statements

The introductions claim annual capacity above50,000 sets,5000-plus customers and30,000-plus projects; the Totim home also gives a30,000m² building-area headline. These are not a reviewed current production or delivery audit. Broad client names, awards and24-hour service wording do not establish a TY-B customer acceptance result or a guaranteed repair time.

Ask which assembly line, inspection method and production slot serve the order. For a critical project, obtain a comparable reference with model, duty and accepted supply scope. Agree lead time and the exact response/attendance/remedy responsibilities in writing rather than using headline counters as contract terms.

Close the offer with replaceable filters and traceable tests

The current TY guide calls for filter cleaning/replacement and routine maintenance, without a fixed interval valid for every dust load. Specify how filter condition is monitored, replacement access and available matching filter/spare parts. Require the selected unit’s wiring/control instructions and documented factory/commissioning checks.

The reviewed pages do not establish a fixed TY-B price, MOQ or model-specific warranty duration. Agree cabinet seals/materials, fan/control parts, filter scope, dimensions, packaging and written defect-remedy terms.

  1. Approve the complete duty

    Freeze airflow/external pressure, filter stage/resistance, sound basis and actual fan/motor/control configuration.

  2. Approve the assembly drawing

    Check dimensions, openings, seals, service space, mounting and materials against the selected designation.

  3. Accept and hand over

    Review traceable test/inspection records, installation checks, filter replacements, spare parts and written service/warranty terms.
