Let's address the elephant in the room first - the AIR 15K5 designation might confuse some buyers. This alphanumeric cocktail actually represents two distinct devices: the Hasee War God K5 Extreme Edition (a gaming powerhouse) and the Lenovo Xiaoxin Air 15 2021 (a productivity workhorse). Think of them as heavyweight boxer vs ballet dancer - both impressive, but built for completely different arenas.
Picture this scenario: You're a computer science student who games on weekends. The Hasee K5's discrete GPU handles your Unity projects and Overwatch SMessions, but its 2.9kg weight might make campus commutes feel like CrossFit training. Meanwhile, the Lenovo Air 15 slips into your backpack like a ninja, lasting through back-to-back lectures - though you'll need cloud gaming for serious playtime.
Both sport 15.6" Full HD screens, but here's the kicker: The Lenovo's 100% sRGB color coverage makes it perfect for digital artists, while the Hasee's standard panel focuses on frame rates over color accuracy. It's like comparing an art gallery to a sports arena - same square footage, completely different experiences.
Let's talk upgrades. The Hasee K5's 8GB RAM ceiling feels like skinny jeans in the age of Chrome tabs - restrictive. Meanwhile, the Lenovo's 32GB expandability is more like cargo pants - ready for whatever you throw at it. Storage-wise, 256GB vs 512GB SSD is the difference between a studio apartment and a loft space for your digital life.
Gaming laptops and battery life go together like oil and water. The Hasee might give you 3-4 hours of Netflix, while the Lenovo's optimized hardware stretches to 8+ hours. Pro tip: Coffee shops have outlets for a reason - choose accordingly based on your nomadic needs.
Here's where it gets interesting. The Hasee K5's older hardware often comes at budget-friendly prices (think $600-800 range), while the Lenovo Air 15 commands premium pricing ($900+) for its modern specs. But wait - used market alert! Refurbished Lenovo units sometimes dip into Hasee's price territory, creating tempting crossover opportunities.
Ultimately, your choice boils down to priorities. Need raw power for gaming or 3D rendering? Hasee's your workhorse. Craving all-day portability for classes or business trips? The Lenovo won't weigh you down. Either way, understanding these specs helps you avoid buying a racehorse when you really need a camel.
You must make sure your specified generator complies with the appropriate ELVby the required date. These are, for: 1. Tranche B specified generators – from 1 January 2019 or when the new specified generator is commissioned 2. Tranche A specified generators – either 1 January 2025 or 1 January 2030 depending on the. . You must meet this ELVby the required date. For engines and turbines the standard ELV for nitrogen oxides is 190mg/Nm3 at a. . The generator must not persistently emit dark smoke. See the guidance on how to identify dark smoke. . Your specified generator must not cause a breach of an air quality standard. You must ensure it protects: 1. human health – known as sensitive. [pdf]
Air permitting for standby generator sets can vary wildly from site to site and when misunderstood can have a major impact on project success. Although EPA regulations have stabilized and are thought to be well understood, ever-increasing local requirements are changing the criticality of air permitting for engine-driven generator sets.
If the engine room temperature exceeds 40°C (104°F), the generator must be derated per the generator derate schedule and cool outside air must be ducted directly to the generator air intake. Alternatively, custom generators can be sized to handle specific ambient conditions.
Spec Note Require generator set vendors to provide documentation demonstrating compliance with applicable limits of U.S. EPA New Source Performance Standards for stationary non-emergency engines. 1. Gasoline engine requirements are same as those for RB LPG. 2. All new engines < 25 hp must be certified to Part 90 on July 1, 2008. 3.
Generators are classed as Tranche A or Tranche B. Read the guidance Specified generator: when you need a permit to check if your static or mobile generator, or a number of generators on your site, require a specified generator environmental permit – some specified generators are excluded from meeting the regulations.
Engine generator set shall meet emissions requirements as determined by AHJ. Type your questions, comments, feedback in the WebEx Q&A box. We will get to as many questions as we can
Large generators, configured with an air inlet positioned high on the generator, will require an additional source of ventilation air. If Ventilation Type 1 or Type 2 is not feasible, an alternative is Type 3; however, this routing configuration will require approximately 50% more airflow than Type 1.
