A buyer searching for Separator Filter is usually trying to stop a bad substitute. A generator is specified by the load in kilowatts, the voltage, the duty, and the noise and emissions of the site. The notes below are selection criteria for a Separator Filter. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Separator Filter
A generator is specified by the load in kilowatts, the voltage, the duty, and the noise and emissions of the site. For a Separator Filter, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Separator Filter is easy to confuse with Generator Oil. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Separator Filter |
|---|---|
| Transfer | Manual or automatic transfer, as a separate device if it is. |
| Load | Running kilowatts and the motor-starting peak. |
| Electrical | Voltage, phases, frequency, and whether it is standby or prime. |
| Fuel | Diesel, gas, or another fuel the site can store legally. |
| Enclosure | Open or canopy, and the noise limit. |
| Runtime | Tank or the fuel supply for the hours you need. |
How to compare two offers
Lay both quotes for Separator Filter on one sheet and line up transfer, load, and electrical. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Separator Filter with a cheaper line that omitted transfer.
Documents worth having before the deposit
Ask for the rating definition: standby and prime are not the same kilowatts. The file should name Separator Filter and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Sizing to the running load and ignoring motor start.
- Treating standby rating as continuous.
- Forgetting the noise limit and the fuel storage rule.
On a Separator Filter, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Separator Filter — Write kilowatts, standby or prime, voltage, fuel, and noise.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like waterproof / IP65 belong
Searches often add a constraint to Separator Filter: waterproof / IP65, or explosion-proof / ATEX. Keep those on this page. IP65 in IEC 60529 means dust-tight and protected against water jets. Write that code if hoses are the real exposure. The word waterproof alone does not name a test. ATEX or IECEx is a certificate for a zone, a gas or dust group, and a temperature class. An IP rating does not grant it. Skip the mark if the site is not hazardous. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Separator Filter include?
Write kilowatts, standby or prime, voltage, fuel, and noise.
Is a cheaper Separator Filter the same part?
Only if transfer, load, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Separator Filter they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
