FAQ
What is the Negative Pressure Weighing Booth mainly used for?
The Negative Pressure Weighing Booth is used to provide clean or controlled airflow for handling samples, powders or operations that need protection from contamination or airborne exposure. It supports pharmaceutical, microbiological, analytical and electronics work.
Which standards and regulations apply to the Negative Pressure Weighing Booth?
The unit is designed with reference to IEC 61010 electrical safety, applicable clean-air and containment standards and relevant GB/T methods. Filters and airflow should be tested periodically. Compliance documentation can be provided on request.
What warranty comes with the Negative Pressure Weighing Booth?
The complete unit carries a 12-month warranty from delivery, covering the main body, core components and controller against manufacturing defects. Consumables and wearing parts such as filters, seals and probes are not covered. Damage from misuse, improper power or unauthorised repair is excluded, and extended warranty can be quoted.
Will staff need special training?
No advanced specialist skills are needed for standard operation, though correct sample handling and safety practice should be followed. We supply a detailed manual and start-up support. For multi-user or regulated sites, a short staff training session can be arranged.
What is the typical lead time for order delivery?
Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Is calibration included?
Regular calibration keeps measurements within the stated accuracy; an annual check is typical, with shorter intervals for heavy or regulated use. Reference standards and procedures are described in the manual. We can quote calibration with certificates.
Where do we get replacement parts?
The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.
Can it be adapted to our requirements?
Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.
How is the Negative Pressure Weighing Booth commissioned?
Benchtop and standard units typically require only placement and connection before use, while larger systems may need professional commissioning. We confirm the installation requirements at order stage. On-site service and training can be provided if needed.
What should be avoided when using the Negative Pressure Weighing Booth?
Do not handle highly toxic or pathogenic agents beyond the containment class, block the face opening or rely on expired filters. Verify airflow and filter integrity. Follow laboratory safety rules.
