01 / Product information and quotations
This website presents the industrial filtration range of Tengyuan Filtration Technology (Langfang) Co., Ltd. under the UPSKY export brand. It helps business customers explore products and request matching or quotation support.
Images, catalogue descriptions and model references are starting points for discussion. Confirm the exact configuration, dimensions, filter media, operating conditions and applicable requirements with us before ordering. A picture or model name alone does not confirm compatibility with your equipment.
Availability, price, lead time, shipping, warranty and other supply conditions must be confirmed in the quotation or order documents for your purchase. A website inquiry is a request for discussion; it does not place an order or create an agreed supply contract.
02 / Selecting equipment for your application
Share the actual application, dust characteristics, temperature, airflow requirements and any special site requirements when requesting equipment selection. Cleaning suitability depends on the cartridge construction, media and condition.
A general product description is not an application-specific engineering approval. Where your process has special hazards or regulatory requirements, identify them during selection and confirm the proposed configuration and supporting documentation before use.
03 / Using website materials and the inquiry form
You may view and download the provided catalogues for product evaluation and procurement discussions. Product images, branding and other website materials remain subject to the rights of their respective owners. Contact Jason if you want to republish materials or use branding in your own marketing.
Please submit accurate business contact details and information you are entitled to share. Do not use the form to send spam, malicious content or material unrelated to a legitimate inquiry.
Our Privacy Notice explains the form's review, verification and sending steps. An on-screen submission confirmation means the delivery service accepted the request; it is not confirmation that a quotation is issued, an order is accepted or a message has been read. If a request is urgent, contact Jason directly.
04 / Downloads and external services
Downloadable catalogues may describe several product configurations. Confirm the current specification for the item you intend to buy, particularly if a catalogue and a quotation differ.
Links to messaging and social platforms take you to external services. Those services have their own terms and availability. If a link, download or inquiry feature is unavailable, email your request directly.
05 / Questions or corrections
If you notice an incorrect product detail or need clarification before making a purchasing decision, contact Jason at jason.filter168@gmail.com. Include the product or page you are referring to.
These terms describe use of this website. Terms for a particular sale are set out separately in the relevant quotation and agreed order documents. Updates to this page will carry a new revision date.
