What buyers should know first
Dusty sites need more than a standard generator rating comparison. Air intake restriction, filter service access, canopy airflow, radiator cleanliness, and maintenance intervals all affect whether a diesel generator can keep running under field conditions.
For Yangzhou Tesla Power Equipment Co., Ltd., the useful RFQ usually starts with load size, duty rating, site conditions, voltage and frequency, enclosure style, control requirements, and the documents the purchaser needs for project approval.
In practice
When a generator will work near mining roads, cement handling, quarry work, or construction traffic, the RFQ should describe the air quality around the set. The supplier can then discuss filtration and enclosure details without guessing.
| Site condition | Risk | What to ask |
|---|---|---|
| Fine dust | Air filter clogging and higher intake restriction | Filter type and service interval guidance |
| Hot dusty yard | Radiator blockage plus reduced cooling margin | Cooling package and cleaning access |
| Container package | Restricted airflow if louvers are poorly arranged | Air inlet and outlet drawing |
| Remote operation | Late maintenance response | Differential pressure or alarm options if required |
Specification points to confirm
- Describe whether dust is occasional, seasonal, or constant during operation.
- Confirm whether the generator is open, silent, or containerized.
- Ask for air inlet and outlet arrangement on soundproof or container sets.
- Check access space for filter replacement and radiator cleaning.
- Request operation and maintenance manuals for site maintenance planning.
Common mistakes to avoid
- Selecting only by kW and ignoring dust, heat, and service access.
- Putting a soundproof set against a wall and blocking air intake.
- Assuming a longer filter interval without describing the site environment.
- Missing spare filter planning for remote sites.
Before requesting a quotation
Ask the supplier to separate the generator set scope from the site installation scope. The generator quotation can normally define the set, enclosure or frame, control panel, breaker, radiator arrangement, silencer, batteries, drawings, and test documents. Civil works, fuel piping, exhaust duct routing, cables, and local approval items should be checked with the site contractor unless they are explicitly included.
- Dust source and expected operating hours per day.
- Ambient temperature range and altitude if relevant.
- Preferred enclosure type and available maintenance clearance.
- Need for spare filters with the first shipment.
- Any engine brand preference such as Cummins, Perkins, Volvo, MTU, or Mitsubishi.

Questions purchasers often ask
Does a dusty site always need a special air filter?
Not always, but the dust level and service plan should be discussed before quotation. The supplier can advise what is practical for the chosen generator package.
Can a silent canopy make dust problems worse?
A canopy can protect equipment, but poor placement may restrict airflow or make cleaning harder. Air inlet, outlet, and access clearance should be checked.
What should be kept on site for maintenance?
Common items include air filters, fuel filters, oil filters, belts, and fluids according to the operation manual and running hours.
Should mining projects choose prime rating?
If the generator supplies regular site power for long hours, prime duty is often more relevant than standby duty. The exact rating should be matched to the load profile.
