Perkins 2806A-E18TAG2 Diesel Engine for 625–650kVA Generator Sets

The Perkins 2806A-E18TAG2 is a 6-cylinder, 18.1-litre inline diesel engine from the 2800 Series, built on Perkins' heavy-duty industrial core and featuring parallel (dual) turbocharging with air-to-air aftercooling. This model is available in two rated speed configurations — 1500rpm and 1800rpm — each representing a separate engine build with distinct performance and fuel consumption characteristics; both are covered under Build List JGBF8028. Designed for the ElectropaK generator drive application, the 2806A-E18TAG2 targets fuel-optimised, non-emissions-regulated markets requiring high power density in a compact footprint.

Build List & Series Compatibility

2806A-E18TAG2 Build List

Both Build Lists refer to the same engine specification. The difference is production batch only — parts compatibility is identical across both designations.

Build List Identification Guide

The Build List is stamped on the engine nameplate, mounted on the rocker cover or timing case. Locate the dataplate and read the alphanumeric string beginning with JGB or JGBF.

Nameplate fields to record before ordering:
· Build List (e.g. JGBF8028or JGB8028)
· Engine Serial Number (ESN)
· Rated speed (1500 or 1800 rpm)
Provide both the Build List and ESN when requesting a quote. This allows us to confirm exact specification match before order commitment.

FAQ

Q1: What generator size (kVA) does the Perkins 2806A-E18TAG2 power?

The 2806A-E18TAG2 is rated to drive generators up to 650kVA Prime / 700kVA Standby at 1500rpm, or 625kVA Prime / 687kVA Standby at 1800rpm, depending on the selected build configuration.

Q2: Should I choose the 1500rpm or 1800rpm version of the 2806A-E18TAG2?

The 1500rpm version delivers higher power output (650kVA Prime) and is typically used in 50Hz markets, while the 1800rpm version (625kVA Prime) is used in 60Hz markets. Both share Build List JGBF8028 but are independent engine builds — confirm your required frequency and rated speed before ordering.

Q3: What is the difference between Prime and Standby power ratings?

Prime power is the maximum output available for variable loads with unlimited annual running hours, while Standby power is a higher-rated output intended for emergency backup use only, typically limited in annual operating hours per the engine's duty classification.

Q4: Is the Perkins 2806A-E18TAG2 emissions certified?

No. The "A" designation indicates a Fuel Optimised, non-emissions-regulated build, intended for markets without mandatory diesel emissions compliance requirements. Buyers in regulated markets (e.g. EU Stage, US EPA Tier) should verify local requirements before purchase.

Q5: Is this a genuine Perkins engine?

Yes. This engine is sourced through an authorized first-tier Perkins distributor channel with full OE specification and documentation.

Q6: What is the lead time to purchase a Perkins 2806A-E18TAG2?

Standard lead time is 3–4 weeks, with formal quotes provided within 24 hours based on configuration, quantity, and delivery terms.

Q7: How does fuel consumption compare between the 1500rpm and 1800rpm versions?

At 100% load, both the 1500rpm and 1800rpm Prime ratings consume 202 g/kWh. The gap widens at partial load — at 50% load, the 1500rpm version consumes 201 g/kWh versus 210 g/kWh for the 1800rpm version, making the 1500rpm build slightly more efficient under lighter, variable loads.
