Yantai Xinglong Pressure Vessel Manufacturing Co., Ltd.；

A: Our air receiver tanks are available in multiple pressure ratings:

● Low Pressure: Up to 10 bar (145 PSI) - suitable for general manufacturing

● Medium Pressure: 10-16 bar (145-232 PSI) - standard industrial operations

● High Pressure: 16-30 bar (232-435 PSI) or higher - specialized applications like PET bottle blowing, laser cutting

Custom pressure ratings can be manufactured according to your specific requirements

A: We manufacture air receiver tanks with capacities ranging from 50 liters to 75,000 liters (approximately 13 to 19,800 gallons). Common sizes include 100L, 200L, 300L, 500L, 1000L, 2000L, 3000L, and larger custom volumes. Both vertical and horizontal orientations are available.

A:Vertical Tanks: Save floor space, better condensate drainage due to gravity, easier installation in compact areas. Recommended for limited space installations.

Horizontal Tanks: Lower center of gravity, easier maintenance access, suitable for outdoor installation or when ceiling height is restricted.

Choice depends on your facility layout, space constraints, and installation preferences.

A: Our air receiver tanks hold multiple international certifications:

ASME U‑Stamp (American Society of Mechanical Engineers) ‑ Required for North American market

CE Marking with PED Certification (Pressure Equipment Directive 2014/68/EU) ‑ Mandatory for European Union

ISO 9001:2015 Quality Management System

Additional certifications available: TUV, UL, CRN (Canada), and other regional standards upon request

ASME Certification: Follows ASME Boiler and Pressure Vessel Code (BPVC), primarily required for the US, Canada, and some Asian markets. Focuses on design, manufacturing, inspection, and testing standards. Requires authorized inspector involvement and U‑stamp application.

CE/PED Certification: Complies with EU Pressure Equipment Directive 2014/68/EU. Equipment with maximum allowable working pressure >0.5 bar must comply. Classification into Category I‑IV based on pressure and volume, with different conformity assessment modules.

Products can be dual‑certified (both ASME U‑stamped and CE‑marked) for global market access.

Test reports are issued for each unit and included in shipment documentation.

A: Absolutely. We welcome and facilitate third‑party inspections from recognized agencies such as:

SGS, Bureau Veritas, Intertek, TÜV Rheinland

Customer‑appointed inspectors

Insurance company surveyors

Inspection can cover visual examination, dimensional checks, witness hydrostatic testing, review of documentation, and packaging verification. Please notify us at least 7 days before the planned inspection date.

A: Yes, we provide both OEM and ODM services:

OEM (Original Equipment Manufacturing): You provide complete design drawings, specifications, and technical requirements. We manufacture according to your exact specifications with your brand/logo.

ODM (Original Design Manufacturing): We provide design support and engineering expertise. You specify functional requirements, and our team develops the product design, which can be customized with your branding.

Both options include custom port configurations, special coatings, unique dimensions, and branded nameplates.

A: MOQ varies by product type and customization level:

‑ Standard Models: MOQ as low as 1‑5 units for regular specifications
