KR‑315 Programmable Dust Test Chamber
Laboratory Standard MIL-STD-810 Blowing Sand and Dust Proof Test Chamber
RT-315 Programmable Laboratory Electronic Part Dustproof Test Chamber is mainly used for testing control cabinets, household appliances, low-voltage electric appliances, automobiles, lamps and lanterns, motorcycle parts, outer shells, etc. The test chamber pressure can be constant and changed, making it suitable for indoor low-concentration dust pollution tests and assessment of sealing and corrosion degrees in this environment.

Product Overview
The KR‑315 programmable dust test chamber is a standard‑compliant environmental simulation device for assessing anti‑dust‑ingress and sealing performance of hardware assemblies. Following GB4706, GB2423, GB7000.1 and IEC 60529 specifications, it reproduces floating and circulating dust‑filled surroundings. It supports both constant‑pressure and variable‑pressure operating modes, and fulfils IP5X / IP6X dust‑proof evaluation demands.
This floor‑standing unit is widely deployed for testing automotive components, lamp housings, household‑appliance enclosures, low‑voltage electrical cabinets, motorcycle parts and control‑module shells. It helps R‑D and QC teams verify sealing reliability, analyse dust‑caused mechanical failure, and provide objective data for product certification and structural optimisation.
Core Product Competitive Advantages
- Durable anti‑abrasion cabinet construction
Inner working cavity adopts SUS304 stainless‑steel sheet, resisting erosion from talcum or cement test‑dust. Outer shell is finished with electrostatic powder‑coated steel plate. Well‑engineered door‑sealing gasket prevents fine‑particle leakage during long‑duration cyclic testing. Built‑in observation window plus internal lamp permit visual sample monitoring without interrupting test sequences.
- Programmable touch‑screen centralised control
Colour HMI touch‑screen manages dust‑blowing motor, dust‑shaking vibrator and full‑test‑timing logic. Operators configure blowing interval, circulation cycles and sample power‑supply timing. Real‑time read‑outs display key running‑parameters for straightforward recipe editing and repeatable test‑profile storage.
- Homogeneous dust‑circulation system
Variable‑frequency high‑pressure blower together with vibration unit prevents dust agglomeration. Dust is evenly suspended across the inner space. Integrated heating‑hose assembly keeps test‑media dry and avoids powder caking which would distort concentration consistency.
- Comprehensive sample‑test auxiliary interfaces
Reserved Φ50 mm feed‑through port with silicone plug allows external wiring for powered‑on specimen testing. On‑board adjustable DC12 V / DC24 V‑20 A output offers continuous or intermittent power supply for energised‑sample assessment. Differential‑pressure vacuum‑pipeline interface supports negative‑pressure‑suction test workflows (vacuum pump supplied by customer).
- Thoughtful mechanical & safety layout
Explosion‑proof‑style door‑handle with locking mechanism ensures tight closure. Equipped with brake‑equipped casters plus levelling feet for convenient relocation and stable static positioning. Multiple embedded sensors monitor temperature‑humidity and air‑speed. Multi‑layer protection prevents motor overload and abnormal operating conditions.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Place the chamber on level workshop ground, lock brake casters. Check door‑gasket integrity, blower, vibrator and sensor function. Load qualified dry test‑dust into the storage bin. Secure specimens onto internal mounting rack; route power / signal cables through reserved feed‑through hole if energised testing is required. Close and securely lock chamber door. Power‑on main unit.
- Program Configuration
On touch‑screen interface set target test‑duration, dust‑blow interval, vibration cycles, and sample‑power‑supply logic. Adjust blower frequency to achieve target dust‑concentration. Confirm vacuum‑pump connection if differential‑pressure test is needed.
- Execute Dust‑Ingress Test
Initiate saved test‑program. The system automatically runs dust‑blowing, vibration‑dispersion and circulation cycles. Operators may observe sample status via viewing window. Equipment stops automatically upon reaching preset test‑time.
- Post‑Test Sample Retrieval & Inspection
Before opening door, complete internal dust‑settling procedure. Open cabinet door, remove test‑pieces. Inspect enclosures and internal components for dust penetration, record sealing‑failure phenomenon for QC‑report.
- Post‑Test Tidying
Thoroughly clean residual test‑dust inside cavity, sieve and circulation‑duct. Check filter elements for clogging. Reset all program‑parameters. Shut‑down power if no further testing tasks. Periodically inspect door‑seal ageing condition and blower working‑status.
